a server name... is there any commonly agreed naming convention for
that??? how should i go about this?

IP addresses consist of only digits and three '.' characters.
Anything else might be a host name.

That should lead you to a solution.

IPV6 address are are little more complex - given that the world is
moving over to IPv6 in a few months then we'll need to consider that....

OK digits and colons...big deal. All he says he wanted to know if it
was a name or address, not how to parse the address into the 32 (V4) or
128 (V6) address value.
