NAME
       NetAddr::IP - Manages IPv4 and IPv6 addresses and subnets

SYNOPSIS
	 use NetAddr::IP qw(
	       Compact
	       Coalesce
	       Zeros
	       Ones
	       V4mask
	       V4net
	       netlimit
	       :aton	       DEPRECATED
	       :lower
	       :upper
	       :old_storable
	       :old_nth
	       :rfc3021
	 );

	 NOTE: NetAddr::IP::Util has a full complement of network address
	       utilities to convert back and forth between binary and text.

	       inet_aton, inet_ntoa, ipv6_aton, ipv6_ntoa
	       ipv6_n2x, ipv6_n2d inet_any2d, inet_n2dx,
	       inet_n2ad, inetanyto6, ipv6to4

       See NetAddr::IP::Util

	 my $ip = new NetAddr::IP '127.0.0.1';
		or if you prefer
	 my $ip = NetAddr::IP->new('127.0.0.1);
	       or from a packed IPv4 address
	 my $ip = new_from_aton NetAddr::IP (inet_aton('127.0.0.1'));
	       or from an octal filtered IPv4 address
	 my $ip = new_no NetAddr::IP '127.012.0.0';

	 print "The address is ", $ip->addr, " with mask ", $ip->mask, "\n" ;

	 if ($ip->within(new NetAddr::IP "127.0.0.0", "255.0.0.0")) {
	     print "Is a loopback address\n";
	 }

				       # This prints 127.0.0.1/32
	 print "You can also say $ip...\n";

       * The following four functions return ipV6 representations of:

	 ::					  = Zeros();
	 FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF  = Ones();
	 FFFF:FFFF:FFFF:FFFF:FFFF:FFFF::	  = V4mask();
	 ::FFFF:FFFF				  = V4net();

       ###### DEPRECATED, will be remove in version 5 ############

	 * To accept addresses in the format as returned by
	 inet_aton, invoke the module as:

	 use NetAddr::IP qw(:aton);

       ###### USE new_from_aton instead ##########################

       * To enable usage of legacy data files containing NetAddr::IP objects stored using the
       Storable module.

	 use NetAddr::IP qw(:old_storable);

       * To compact many smaller subnets (see: "$me->compact($addr1,$addr2,...)"

	 @compacted_object_list = Compact(@object_list)

       * Return a reference to list of "NetAddr::IP" subnets of $masklen mask length, when
       $number or more addresses from @list_of_subnets are found to be contained in said subnet.

	 $arrayref = Coalesce($masklen, $number, @list_of_subnets)

       * By default NetAddr::IP functions and methods return string IPv6 addresses in uppercase.
       To change that to lowercase:

       NOTE: the AUGUST 2010 RFC5952 states:

	   4.3. Lowercase

	     The characters "a", "b", "c", "d", "e", and "f" in an IPv6
	     address MUST be represented in lowercase.

       It is recommended that all NEW applications using NetAddr::IP be invoked as shown on the
       next line.

	 use NetAddr::IP qw(:lower);

       * To ensure the current IPv6 string case behavior even if the default changes:

	 use NetAddr::IP qw(:upper);

       * To set a limit on the size of nets processed or returned by NetAddr::IP.

       Set the maximum number of nets beyond which NetAddr::IP will return an error as a power of
       2 (default 16 or 65536 nets). Each 2**16 consumes approximately 4 megs of memory. A 2**20
       consumes 64 megs of memory, A 2**24 consumes 1 gigabyte of memory.

	 use NetAddr::IP qw(netlimit);
	 netlimit 20;

       The maximum netlimit allowed is 2**24. Attempts to set limits below the default of 16 or
       above the maximum of 24 are ignored.

       Returns true on success, otherwise "undef".

INSTALLATION
       Un-tar the distribution in an appropriate directory and type:

	       perl Makefile.PL
	       make
	       make test
	       make install

       NetAddr::IP depends on NetAddr::IP::Util which installs by default with its primary
       functions compiled using Perl's XS extensions to build a C library. If you do not have a C
       complier available or would like the slower Pure Perl version for some other reason, then
       type:

	       perl Makefile.PL -noxs
	       make
	       make test
	       make install

DESCRIPTION
       This module provides an object-oriented abstraction on top of IP addresses or IP subnets
       that allows for easy manipulations.  Version 4.xx of NetAddr::IP will work with older
       versions of Perl and is compatible with Math::BigInt.

       The internal representation of all IP objects is in 128 bit IPv6 notation.  IPv4 and IPv6
       objects may be freely mixed.

   Overloaded Operators
       Many operators have been overloaded, as described below:

       Assignment ("=")
	   Has been optimized to copy one NetAddr::IP object to another very quickly.

       "->copy()"
	   The assignment ("=") operation is only put in to operation when the copied object is
	   further mutated by another overloaded operation. See overload SPECIAL SYMBOLS FOR "use
	   overload" for details.

	   "->copy()" actually creates a new object when called.

       Stringification
	   An object can be used just as a string. For instance, the following code

		   my $ip = new NetAddr::IP '192.168.1.123';
		   print "$ip\n";

	   Will print the string 192.168.1.123/32.

       Equality
	   You can test for equality with either "eq" or "==". "eq" allows comparison with
	   arbitrary strings as well as NetAddr::IP objects. The following example:

	       if (NetAddr::IP->new('127.0.0.1','255.0.0.0') eq '127.0.0.1/8')
		  { print "Yes\n"; }

	   will print out "Yes".

	   Comparison with "==" requires both operands to be NetAddr::IP objects.

	   In both cases, a true value is returned if the CIDR representation of the operands is
	   equal.

       Comparison via >, <, >=, <=, <=> and "cmp"
	   Internally, all network objects are represented in 128 bit format.  The numeric
	   representation of the network is compared through the corresponding operation.
	   Comparisons are tried first on the address portion of the object and if that is equal
	   then the NUMERIC cidr portion of the masks are compared. This leads to the
	   counterintuitive result that

		   /24 > /16

	   Comparison should not be done on netaddr objects with different CIDR as this may
	   produce indeterminate - unexpected results, rather the determination of which netblock
	   is larger or smaller should be done by comparing

		   $ip1->masklen <=> $ip2->masklen

       Addition of a constant ("+")
	   Add a 32 bit signed constant to the address part of a NetAddr object.  This operation
	   changes the address part to point so many hosts above the current objects start
	   address. For instance, this code:

	       print NetAddr::IP->new('127.0.0.1/8') + 5;

	   will output 127.0.0.6/8. The address will wrap around at the broadcast back to the
	   network address. This code:

	       print NetAddr::IP->new('10.0.0.1/24') + 255;

	       outputs 10.0.0.0/24.

	   Returns the the unchanged object when the constant is missing or out of range.

	       2147483647 <= constant >= -2147483648

       Subtraction of a constant ("-")
	   The complement of the addition of a constant.

       Difference ("-")
	   Returns the difference between the address parts of two NetAddr::IP objects address
	   parts as a 32 bit signed number.

	   Returns undef if the difference is out of range.

	   (See range restrictions on Addition above)

       Auto-increment
	   Auto-incrementing a NetAddr::IP object causes the address part to be adjusted to the
	   next host address within the subnet. It will wrap at the broadcast address and start
	   again from the network address.

       Auto-decrement
	   Auto-decrementing a NetAddr::IP object performs exactly the opposite of auto-
	   incrementing it, as you would expect.

   Serializing and Deserializing
       This module defines hooks to collaborate with Storable for serializing "NetAddr::IP"
       objects, through compact and human readable strings. You can revert to the old format by
       invoking this module as

	 use NetAddr::IP ':old_storable';

       You must do this if you have legacy data files containing NetAddr::IP objects stored using
       the Storable module.

   Methods
       "->new([$addr, [ $mask|IPv6 ]])"
       "->new6([$addr, [ $mask]])"
       "->new_no([$addr, [ $mask]])"
       "->new_from_aton($netaddr)"
       new_cis and new_cis6 are DEPRECATED
       "->new_cis("$addr $mask)"
       "->new_cis6("$addr $mask)"
	   The first two methods create a new address with the supplied address in $addr and an
	   optional netmask $mask, which can be omitted to get a /32 or /128 netmask for IPv4 /
	   IPv6 addresses respectively.

	   The third method "new_no" is exclusively for IPv4 addresses and filters improperly
	   formatted dot quad strings for leading 0's that would normally be interpreted as octal
	   format by NetAddr per the specifications for inet_aton.

	   new_from_aton takes a packed IPv4 address and assumes a /32 mask. This function
	   replaces the DEPRECATED :aton functionality which is fundamentally broken.

	   The last two methods new_cis and new_cis6 differ from new and new6 only in that they
	   except the common Cisco address notation for address/mask pairs with a space as a
	   separator instead of a slash (/)

	   These methods are DEPRECATED because the functionality is now included in the other
	   "new" methods

	     i.e.  ->new_cis('1.2.3.0 24')
		   or
		   ->new_cis6('::1.2.3.0 120')

	   "->new6" and "->new_cis6" mark the address as being in ipV6 address space even if the
	   format would suggest otherwise.

	     i.e.  ->new6('1.2.3.4') will result in ::102:304

	     addresses submitted to ->new in ipV6 notation will
	     remain in that notation permanently. i.e.
		   ->new('::1.2.3.4') will result in ::102:304
	     whereas new('1.2.3.4') would print out as 1.2.3.4

	     See "STRINGIFICATION" below.

	   $addr can be almost anything that can be resolved to an IP address in all the
	   notations I have seen over time. It can optionally contain the mask in CIDR notation.

	   prefix notation is understood, with the limitation that the range specified by the
	   prefix must match with a valid subnet.

	   Addresses in the same format returned by "inet_aton" or "gethostbyname" can also be
	   understood, although no mask can be specified for them. The default is to not attempt
	   to recognize this format, as it seems to be seldom used.

	   To accept addresses in that format, invoke the module as in

	     use NetAddr::IP ':aton'

	   If called with no arguments, 'default' is assumed.

	   If called with an empty string as the argument, returns 'undef'

	   $addr can be any of the following and possibly more...

	     n.n
	     n.n/mm
	     n.n.n
	     n.n.n/mm
	     n.n.n.n
	     n.n.n.n/mm 	   32 bit cidr notation
	     n.n.n.n/m.m.m.m
	     loopback, localhost, broadcast, any, default
	     x.x.x.x/host
	     0xABCDEF, 0b111111000101011110, (a bcd number)
	     a netaddr as returned by 'inet_aton'

	   Any RFC1884 notation

	     ::n.n.n.n
	     ::n.n.n.n/mmm	   128 bit cidr notation
	     ::n.n.n.n/::m.m.m.m
	     ::x:x
	     ::x:x/mmm
	     x:x:x:x:x:x:x:x
	     x:x:x:x:x:x:x:x/mmm
	     x:x:x:x:x:x:x:x/m:m:m:m:m:m:m:m any RFC1884 notation
	     loopback, localhost, unspecified, any, default
	     ::x:x/host
	     0xABCDEF, 0b111111000101011110 within the limits
	     of perl's number resolution
	     123456789012  a 'big' bcd number (bigger than perl likes)
	     and Math::BigInt

	   If called with no arguments, 'default' is assumed.

	   If called with an empty string as the argument, returns 'undef'

       "->broadcast()"
	   Returns a new object referring to the broadcast address of a given subnet. The
	   broadcast address has all ones in all the bit positions where the netmask has zero
	   bits. This is normally used to address all the hosts in a given subnet.

       "->network()"
	   Returns a new object referring to the network address of a given subnet. A network
	   address has all zero bits where the bits of the netmask are zero. Normally this is
	   used to refer to a subnet.

       "->addr()"
	   Returns a scalar with the address part of the object as an IPv4 or IPv6 text string as
	   appropriate. This is useful for printing or for passing the address part of the
	   NetAddr::IP object to other components that expect an IP address. If the object is an
	   ipV6 address or was created using ->new6($ip) it will be reported in ipV6 hex format
	   otherwise it will be reported in dot quad format only if it resides in ipV4 address
	   space.

       "->mask()"
	   Returns a scalar with the mask as an IPv4 or IPv6 text string as described above.

       "->masklen()"
	   Returns a scalar the number of one bits in the mask.

       "->bits()"
	   Returns the width of the address in bits. Normally 32 for v4 and 128 for v6.

       "->version()"
	   Returns the version of the address or subnet. Currently this can be either 4 or 6.

       "->cidr()"
	   Returns a scalar with the address and mask in CIDR notation. A NetAddr::IP object
	   stringifies to the result of this function.	(see comments about ->new6() and ->addr()
	   for output formats)

       "->aton()"
	   Returns the address part of the NetAddr::IP object in the same format as the
	   "inet_aton()" or "ipv6_aton" function respectively. If the object was created using
	   ->new6($ip), the address returned will always be in ipV6 format, even for addresses in
	   ipV4 address space.

       "->range()"
	   Returns a scalar with the base address and the broadcast address separated by a dash
	   and spaces. This is called range notation.

       "->prefix()"
	   Returns a scalar with the address and mask in ipV4 prefix representation. This is
	   useful for some programs, which expect its input to be in this format. This method
	   will include the broadcast address in the encoding.

       "->nprefix()"
	   Just as "->prefix()", but does not include the broadcast address.

       "->numeric()"
	   When called in a scalar context, will return a numeric representation of the address
	   part of the IP address. When called in an array contest, it returns a list of two
	   elements. The first element is as described, the second element is the numeric
	   representation of the netmask.

	   This method is essential for serializing the representation of a subnet.

       "->bigint()"
	   When called in scalar context, will return a Math::BigInt representation of the
	   address part of the IP address. When called in an array context, it returns a list of
	   two elements, The first element is as described, the second element is the
	   Math::BigInt representation of the netmask.

       "->wildcard()"
	   When called in a scalar context, returns the wildcard bits corresponding to the mask,
	   in dotted-quad or ipV6 format as applicable.

	   When called in an array context, returns a two-element array. The first element, is
	   the address part. The second element, is the wildcard translation of the mask.

       "->short()"
	   Returns the address part in a short or compact notation.

	     (ie, 127.0.0.1 becomes 127.1).

	   Works with both, V4 and V6.

       "->full()"
	   Returns the address part in FULL notation for ipV4 and ipV6 respectively.

	     i.e. for ipV4
	       0000:0000:0000:0000:0000:0000:127.0.0.1

		  for ipV6
	       0000:0000:0000:0000:0000:0000:0000:0000

	   To force ipV4 addresses into full ipV6 format use:

       "->full6()"
	   Returns the address part in FULL ipV6 notation

       "$me->contains($other)"
	   Returns true when $me completely contains $other. False is returned otherwise and
	   "undef" is returned if $me and $other are not both "NetAddr::IP" objects.

       "$me->within($other)"
	   The complement of "->contains()". Returns true when $me is completely contained within
	   $other.

	   Note that $me and $other must be "NetAddr::IP" objects.

       C->is_rfc1918()>
	   Returns true when $me is an RFC 1918 address.

	     10.0.0.0	   -   10.255.255.255  (10/8 prefix)
	     172.16.0.0    -   172.31.255.255  (172.16/12 prefix)
	     192.168.0.0   -   192.168.255.255 (192.168/16 prefix)

       "->splitref($bits,[optional $bits1,$bits2,...])"
	   Returns a reference to a list of objects, representing subnets of "bits" mask produced
	   by splitting the original object, which is left unchanged. Note that $bits must be
	   longer than the original mask in order for it to be splittable.

	   ERROR conditions:

	     ->splitref will DIE with the message 'netlimit exceeded'
	       if the number of return objects exceeds 'netlimit'.
	       See function 'netlimit' above (default 2**16 or 65536 nets).

	     ->splitref returns undef when C<bits> or the (bits list)
	       will not fit within the original object.

	     ->splitref returns undef if a supplied ipV4, ipV6, or NetAddr
	       mask in inappropriately formatted,

	   bits may be a CIDR mask, a dot quad or ipV6 string or a NetAddr::IP object.	If "bits"
	   is missing, the object is split for into all available addresses within the ipV4 or
	   ipV6 object ( auto-mask of CIDR 32, 128 respectively ).

	   With optional additional "bits" list, the original object is split into parts sized
	   based on the list. NOTE: a short list will replicate the last item. If the last item
	   is too large to for what remains of the object after splitting off the first parts of
	   the list, a "best fits" list of remaining objects will be returned based on an
	   increasing sort of the CIDR values of the "bits" list.

	     i.e.  my $ip = new NetAddr::IP('192.168.0.0/24');
		   my $objptr = $ip->split(28, 29, 28, 29, 26);

	      has split plan 28 29 28 29 26 26 26 28
	      and returns this list of objects

		   192.168.0.0/28
		   192.168.0.16/29
		   192.168.0.24/28
		   192.168.0.40/29
		   192.168.0.48/26
		   192.168.0.112/26
		   192.168.0.176/26
		   192.168.0.240/28

	   NOTE: that /26 replicates twice beyond the original request and /28 fills the
	   remaining return object requirement.

       "->rsplitref($bits,[optional $bits1,$bits2,...])"
	   "->rsplitref" is the same as "->splitref" above except that the split plan is applied
	   to the original object in reverse order.

	     i.e.  my $ip = new NetAddr::IP('192.168.0.0/24');
		   my @objects = $ip->split(28, 29, 28, 29, 26);

	      has split plan 28 26 26 26 29 28 29 28
	      and returns this list of objects

		   192.168.0.0/28
		   192.168.0.16/26
		   192.168.0.80/26
		   192.168.0.144/26
		   192.168.0.208/29
		   192.168.0.216/28
		   192.168.0.232/29
		   192.168.0.240/28

       "->split($bits,[optional $bits1,$bits2,...])"
	   Similar to "->splitref" above but returns the list rather than a list reference. You
	   may not want to use this if a large number of objects is expected.

       "->rsplit($bits,[optional $bits1,$bits2,...])"
	   Similar to "->rsplitref" above but returns the list rather than a list reference. You
	   may not want to use this if a large number of objects is expected.

       "->hostenum()"
	   Returns the list of hosts within a subnet.

	   ERROR conditions:

	     ->hostenum will DIE with the message 'netlimit exceeded'
	       if the number of return objects exceeds 'netlimit'.
	       See function 'netlimit' above (default 2**16 or 65536 nets).

       "->hostenumref()"
	   Faster version of "->hostenum()", returning a reference to a list.

	   NOTE: hostenum and hostenumref report zero (0) useable hosts in a /31 network. This is
	   the behavior expected prior to RFC 3021. To report 2 useable hosts for use in point-
	   to-point networks, use :rfc3021 tag.

		   use NetAddr::IP qw(:rfc3021);

	   This will cause hostenum and hostenumref to return two (2) useable hosts in a /31
	   network.

       "$me->compact($addr1, $addr2, ...)"
       "@compacted_object_list = Compact(@object_list)"
	   Given a list of objects (including $me), this method will compact all the addresses
	   and subnets into the largest (ie, least specific) subnets possible that contain
	   exactly all of the given objects.

	   Note that in versions prior to 3.02, if fed with the same IP subnets multiple times,
	   these subnets would be returned. From 3.02 on, a more "correct" approach has been
	   adopted and only one address would be returned.

	   Note that $me and all $addr's must be "NetAddr::IP" objects.

       "$me->compactref(\@list)"
       "$compacted_object_list = Compact(\@list)"
	   As usual, a faster version of "->compact()" that returns a reference to a list. Note
	   that this method takes a reference to a list instead.

	   Note that $me must be a "NetAddr::IP" object.

       "$me->coalesce($masklen, $number, @list_of_subnets)"
       "$arrayref = Coalesce($masklen,$number,@list_of_subnets)"
	   Will return a reference to list of "NetAddr::IP" subnets of $masklen mask length, when
	   $number or more addresses from @list_of_subnets are found to be contained in said
	   subnet.

	   Subnets from @list_of_subnets with a mask shorter than $masklen are passed "as is" to
	   the return list.

	   Subnets from @list_of_subnets with a mask longer than $masklen will be counted
	   (actually, the number of IP addresses is counted) towards $number.

	   Called as a method, the array will include $me.

	   WARNING: the list of subnet must be the same type. i.e ipV4 or ipV6

       "->first()"
	   Returns a new object representing the first usable IP address within the subnet (ie,
	   the first host address).

       "->last()"
	   Returns a new object representing the last usable IP address within the subnet (ie,
	   one less than the broadcast address).

       "->nth($index)"
	   Returns a new object representing the n-th usable IP address within the subnet (ie,
	   the n-th host address).  If no address is available (for example, when the network is
	   too small for $index hosts), "undef" is returned.

	   Version 4.00 of NetAddr::IP and version 1.00 of NetAddr::IP::Lite implements
	   "->nth($index)" and "->num()" exactly as the documentation states.  Previous versions
	   behaved slightly differently and not in a consistent manner. See the README file for
	   details.

	   To use the old behavior for "->nth($index)" and "->num()":

	     use NetAddr::IP::Lite qw(:old_nth);

	     old behavior:
	     NetAddr::IP->new('10/32')->nth(0) == undef
	     NetAddr::IP->new('10/32')->nth(1) == undef
	     NetAddr::IP->new('10/31')->nth(0) == undef
	     NetAddr::IP->new('10/31')->nth(1) == 10.0.0.1/31
	     NetAddr::IP->new('10/30')->nth(0) == undef
	     NetAddr::IP->new('10/30')->nth(1) == 10.0.0.1/30
	     NetAddr::IP->new('10/30')->nth(2) == 10.0.0.2/30
	     NetAddr::IP->new('10/30')->nth(3) == 10.0.0.3/30

	   Note that in each case, the broadcast address is represented in the output set and
	   that the 'zero'th index is alway undef except for a point-to-point /31 or /127 network
	   where there are exactly two addresses in the network.

	     new behavior:
	     NetAddr::IP->new('10/32')->nth(0)	== 10.0.0.0/32
	     NetAddr::IP->new('10.1/32'->nth(0) == 10.0.0.1/32
	     NetAddr::IP->new('10/31')->nth(0)	== 10.0.0.0/32
	     NetAddr::IP->new('10/31')->nth(1)	== 10.0.0.1/32
	     NetAddr::IP->new('10/30')->nth(0) == 10.0.0.1/30
	     NetAddr::IP->new('10/30')->nth(1) == 10.0.0.2/30
	     NetAddr::IP->new('10/30')->nth(2) == undef

	   Note that a /32 net always has 1 usable address while a /31 has exactly two usable
	   addresses for point-to-point addressing. The first index (0) returns the address
	   immediately following the network address except for a /31 or /127 when it return the
	   network address.

       "->num()"
	   As of version 4.42 of NetAddr::IP and version 1.27 of NetAddr::IP::Lite a /31 and /127
	   with return a net num value of 2 instead of 0 (zero) for point-to-point networks.

	   Version 4.00 of NetAddr::IP and version 1.00 of NetAddr::IP::Lite return the number of
	   usable IP addresses within the subnet, not counting the broadcast or network address.

	   Previous versions worked only for ipV4 addresses, returned a maximum span of 2**32 and
	   returned the number of IP addresses not counting the broadcast address.
		   (one greater than the new behavior)

	   To use the old behavior for "->nth($index)" and "->num()":

	     use NetAddr::IP::Lite qw(:old_nth);

	   WARNING:

	   NetAddr::IP will calculate and return a numeric string for network ranges as large as
	   2**128. These values are TEXT strings and perl can treat them as integers for numeric
	   calculations.

	   Perl on 32 bit platforms only handles integer numbers up to 2**32 and on 64 bit
	   platforms to 2**64.

	   If you wish to manipulate numeric strings returned by NetAddr::IP that are larger than
	   2**32 or 2**64, respectively,  you must load additional modules such as Math::BigInt,
	   bignum or some similar package to do the integer math.

       "->re()"
	   Returns a Perl regular expression that will match an IP address within the given
	   subnet. Defaults to ipV4 notation. Will return an ipV6 regex if the address in not in
	   ipV4 space.

       "->re6()"
	   Returns a Perl regular expression that will match an IP address within the given
	   subnet. Always returns an ipV6 regex.

EXPORT_OK
	       Compact
	       Coalesce
	       Zeros

NOTES / BUGS ... FEATURES
       NetAddr::IP only runs in Pure Perl mode on Windows boxes because I don't have the
       resources or know how to get the "configure" stuff working in the Windows environment.
       Volunteers WELCOME to port the "C" portion of this module to Windows.
