	Just to close the loop...

<?php
function dnsbl_lookup($ip, $bl) {
	if ($ip) {
		$rip = implode('.', array_reverse(explode('.',$ip)));
		return gethostbyname("$rip.$bl");
	} else {
		return 'ERR';
	}
}

switch (dnsbl_lookup($_GET['ip'], 'sbl-xbl.spamhaus.org')) {
	case '127.0.0.2' :
		// SBL
		break;
	case '127.0.0.4' :
	case '127.0.0.5' :
	case '127.0.0.6' :
		// XBL
		break;
	default	:
		// not found
	}
?>
