PRIPS(1) BSD General Commands Manual PRIPS(1)NAME
prips -- print the IP addresses in a given range
SYNOPSIS
prips [-c] [-d delim] [-e exclude] [-f format] [-i incr] start end
prips [-c] [-d delim] [-e exclude] [-f format] [-i incr] CIDR-block
prips -h
DESCRIPTION
The prips tool can be used to print all of the IP addresses in a given range. It can enhance tools that only work on one host at a time,
e.g. whois(1).
The prips tool accepts the following command-line options:
-c Print the range in CIDR notation.
-d delim
Set the delimiter to the character with ASCII code delim where 0 <= delim <= 255.
-e <x.x.x,x.x>
Exclude ranges from the output.
-f format
Set the format of addresses (hex, dec, or dot).
-h Show summary of options.
-i incr
Set the increment to 'x'.
ENVIRONMENT
The prips tool's operation is not influenced by any environment variables.
FILES
The prips tool's operation is not influenced by any files.
EXAMPLES
Display all the addresses in a reserved subnet:
prips 192.168.32.0 192.168.32.255
The same, using CIDR notation:
prips 192.168.32/24
Display only the usable addresses in a class A reserved subnet using a space instead of a newline for a delimiter:
prips -d 32 10.0.0.1 10.255.255.255
Display every fourth address in a weird block:
prips -i 4 192.168.32.7 192.168.33.5
Determine the smallest CIDR block containing two addresses:
prips -c 192.168.32.5 192.168.32.11
DIAGNOSTICS
The prips utility exits 0 on success, and >0 if an error occurs.

HISTORY
The prips tool was originally written by Daniel Kelly and later adopted by Peter Pentchev. This manual page was originally written by Juan
Alvarez for the Debian GNU/Linux system and later added to the prips distribution and converted to mdoc format by Peter Pentchev.

IPv4Addr(3) User Contributed Perl Documentation IPv4Addr(3)NAME
Net::IPv4Addr - Perl extension for manipulating IPv4 addresses.
SYNOPSIS
use Net::IPv4Addr qw( :all );
my ($ip,$cidr) = ipv4_parse( "127.0.0.1/24" );
my ($ip,$cidr) = ipv4_parse( "192.168.100.10 / 255.255.255.0" );
my ($net,$msk) = ipv4_network( "192.168.100.30" );
my $broadcast = ipv4_broadcast( "192.168.100.30/26" );
if ( ipv4_in_network( "192.168.100.0", $her_ip ) ) {
print "Welcome !";
}
etc.
DESCRIPTION
Net::IPv4Addr provides functions for parsing IPv4 addresses both in traditional address/netmask format and in the new CIDR format. There
are also methods for calculating the network and broadcast address and also to see check if a given address is in a specific network.
ADDRESSES
All of Net::IPv4Addr functions accepts addresses in many format. The parsing is very liberal.
All these addresses would be accepted:
127.0.0.1
192.168.001.010/24
192.168.10.10/255.255.255.0
192.168.30.10 / 21
10.0.0.0 / 255.0.0.0
255.255.0.0
Those wouldn't though:
272.135.234.0
192.168/16
Most functions accepts the address and netmask or masklength in the same scalar value or as separate values. That is either
my($ip,$masklength) = ipv4_parse($cidr_str);
my($ip,$masklength) = ipv4_parse($ip_str,$msk_str);
USING
No functions are exported by default. Either use the ":all" tag to import them all or explicitly import those you need.
FUNCTIONS
ipv4_parse
my ($ip,$msklen) = ipv4_parse($cidr_str);
my $cidr = ipv4_parse($ip_str,$msk_str);
my ($ip) = ipv4_parse($ip_str,$msk_str);
Parse an IPv4 address and in scalar context the address in CIDR format and in an array context the address and the mask length.
If the parameters doesn't contains a netmask or a mask length, in scalar context only the IPv4 address is returned and in an array
context the mask length is undefined.
If the function cannot parse its input, it croaks. Trap it using "eval" if don't like that.
ipv4_network
my $cidr = ipv4_network($ip_str);
my $cidr = ipv4_network($cidr_str);
my ($net,$msk) = ipv4_network( $net_str, $msk_str);
In scalar context, this function returns the network in CIDR format in which the address is. In array context, it returns the network
address and its mask length as a two elements array. If the input is an host without a netmask of mask length, the default netmask is
assumed.
Again, the function croak if the input is invalid.
ipv4_broadcast
my ($broadcast) = ipv4_broadcast($ip_str);
my $broadcast = ipv4_broadcast($ip_str,$msk_str);
This function returns the broadcast address. If the input doesn't contains a netmask or mask length, the default netmask is assumed.
This function croaks if the input is invalid.
ipv4_network
my $cidr = ipv4_network($net_str);
my $cidr = ipv4_network($cidr_sstr);
my ($net,$msk) = ipv4_network( $ip_str, $mask_str);
In scalar context, this function returns the network in CIDR format in which the address is. In array context, it returns the network
address and its mask length as a two elements array. If the input is an host without a netmask or mask length, the default netmask is
assumed.
Again, the function croak if the input is invalid.
ipv4_in_network
print "Yes" if ipv4_in_network( $cidr_str1, $cidr_str2);
print "Yes" if ipv4_in_network( $ip_str1, $mask_str1, $cidr_str2 );
print "Yes" if ipv4_in_network( $ip1, $mask1, $ip2, $msk2 );
This function checks if the second network is contained in the first one and it implements the following semantics :
If net1 or net2 is a magic address (0.0.0.0 or 255.255.255.255)
than this function returns true.
If net1 is an host, net2 will be in the same net only if
it is the same host.
If net2 is an host, it will be contained in net1 only if
it is part of net1.
If net2 is only part of net1 if it is entirely contained in
net1.
Trap bad input with "eval" or else.
ipv4_checkip
if ($ip = ipv4_checkip($str) ) {
# Do something
}
Return the IPv4 address in the string or undef if the input doesn't contains a valid IPv4 address.
ipv4_cidr2msk
my $netmask = ipv4_cidr2msk( $cidr );
Returns the netmask corresponding to the mask length given in input. As usual, croaks if it doesn't like your input (in this case a
number between 0 and 32).
ipv4_msk2cidr
my $masklen = ipv4_msk2cidr( $msk );
Returns the mask length of the netmask in input. As usual, croaks if it doesn't like your input.
