Optimization

I don't know if "gethotbyname" is a fast function, but you can change this:

if (gethostbyname($addr) == $addr) {
self::throwError('Error: Domain name is unresolvable or IP address is invalid!');
} else {
$addr = gethostbyname($addr);
}


For this:

$originalAddr = gethostbyname($addr);
if ($originalAddr == $addr) {
self::throwError('Error: Domain name is unresolvable or IP address is invalid!');
} else {
$addr = $originalAddr;
}

Hi Ruben,

You're absolutely right!

I'll commit this change now.

"gethostbyname" is not good for performance, especially when used twice unnecessarily.

Thanks a lot,
Radovan.

you're welcome!

Regards :)
