regex libraries are indeed a useful resource for this kind of questions. You get a lot of differenz solutions - and a good idea how to implement it the way you need.

A: 

Ping/nslookup the hostname the user provides.

If that works out well, you might want to try opening a connection to the hostname on port 80.
