use APR::IpSubnet (); my $ipsub = APR::IpSubnet->new($pool, "127.0.0.1"); $ok = $ipsub->test($sock_addr);
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
APR::IpSubnet provides the following functions and/or methods:
Create an IP subnet represenation object
$ipsubnet = APR::IpSubnet->new($pool, $ip); $ipsubnet = APR::IpSubnet->new($pool, $ip, $mask_or_numbits);
$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.
$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.
The IP-subnet object
Test the IP address in the socket address object against a pre-built ip-subnet representation.
$ret = $ipsub->test($sockaddr);
The ip-subnet representation
The socket address to test
$ret( boolean )
true if the socket address is within the subnet, false otherwise
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 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);
