use Net::GrpNetworks;
$grpnet = new Net::GrpNetworks();
$grpnet->add("New York", "210.210.10.0", "255.255.255.0");
$grpnet->add("New York", "210.210.11.0", "255.255.255.0");
$grpnet->add("New York", "210.210.12.0", "255.255.254.0");
$grpnet->add("Rio de Janeiro", "200.255.49.128", "255.255.255.128");
$grpnet->add("Rio de Janeiro", "200.255.50.0", "255.255.252.0");
$grpnet->add("Rio de Janeiro", "200.255.60.0", "255.255.255.0");
$City = $grpnet->find("200.255.60.10");  # $City will be set to "Rio de Janeiro"
if ( $City = $grpnet->find("210.210.9.5") ) # Will be false
