README

CIDR match

CIDRmatch is a library to match an IP to an IP range in CIDR notation (IPv4 and IPv6).

NOTE: Symfony2 already does everything this library here does with its IpUtils module. Unfortunately I discovered this only after I finished working on this library.

Usage

$cidrMatch = new CIDRmatch();
$cidrMatch->match($ip, $cidr);

Tests

./vendor/bin/phpunit tests/CIDRmatchTest
