You could try converting to long IP addresses and comparing that way: <?php // To actually get the long IP address that you can use in http:// // you sometimes need to use something like printf("%u\n", ip2long($ip)); // See also: http://us3.php.net/manual/en/function.ip2long.php $startip = "192.168.0.5"; $endip = "192.168.0.16"; $targetip = "192.168.0.7"; $startlong = ip2long($startip); $endlong = ip2long($endip); $targetlong = ip2long($targetip); if ($startlong <= $targetlong AND $targetlong <= $endlong) echo "within range"; else echo "out of range"; ?> = = = Original message = = = Does anyone have a function that will check if an ip address falls with a starting/ending ip address range>> Thanks, Dave ___________________________________________________________ Sent by ePrompter, the premier email notification software.
