"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);
