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);
