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:
newCreate 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
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
testTest 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.
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);
