Hello Java Ranchers!

I have written one small Java program to validate a domain name.
Below is the code attached.




Just want to know if this DNS lookup from a java code can be blocked by a firewall or not.

Many Thanks,
Anant

Don't use javax.naming for DNS lookups; use http://www.xbill.org/dnsjava/

Outgoing DNS lookups *can* be blocked, but they generally aren't. All machines must do them periodically, so this would cause more problems than it would solve.
