NAME

       APR::IpSubnet - Perl API for accessing APRs ip_subnet structures

Synopsis
	 use APR::IpSubnet ();

	 my $ipsub = APR::IpSubnet->new($pool, "127.0.0.1");
	 $ok = $ipsub->test($sock_addr);

Description
       "APR::IpSubnet" object represents a range of IP addresses (IPv4/IPv6). A socket connection can be matched against this range to test
       whether the IP it's coming from is inside or outside of this range.

API

       "APR::IpSubnet" provides the following functions and/or methods:

   "new"
       Create an IP subnet represenation object

	 $ipsubnet = APR::IpSubnet->new($pool, $ip);
	 $ipsubnet = APR::IpSubnet->new($pool, $ip, $mask_or_numbits);

       obj: "APR::IpSubnet" (class name)
       arg1: $pool ( "APR::Pool object" )
       arg2: $ip ( string )
	   IP address in one of the two formats: IPv4 (e.g. "127.0.0.1") or IPv6 (e.g. "::1"). IPv6 addresses are accepted only if APR has the
	   IPv6 support enabled.

       opt arg3: $mask_or_numbits ( string )
	   An optional IP mask (e.g. "255.0.0.0") or number of bits (e.g. "15").

	   If none provided, the default is not to mask off.

       ret: $ret ( "APR::IpSubnet object" )
	   The IP-subnet object

       excpt: "APR::Error"
       since: 2.0.00

   "test"
       Test the IP address in the socket address object against a pre-built ip-subnet representation.

	 $ret = $ipsub->test($sockaddr);

       obj: $ipsub ( "APR::IpSubnet object" )
	   The ip-subnet representation

       arg1: $sockaddr ( "APR::SockAddr object" )
	   The socket address to test

       ret: $ret ( boolean )
	   true if the socket address is within the subnet, false otherwise

       since: 2.0.00

       This method is used for testing whether or not an address is within a subnet. It's used by module "mod_access" to check whether the client
       IP fits into the IP range, supplied by "Allow"/"Deny" directives.

       Example:

       Allow accesses only from the localhost (IPv4):

	 use APR::IpSubnet ();
	 use Apache2::Connection ();
	 use Apache2::RequestRec ();
	 my $ipsub = APR::IpSubnet->new($r->pool, "127.0.0.1");
	 ok $ipsub->test($r->connection->remote_addr);
