Determining The Validity of a Hostname

Hello Again,

I need to determine whether a set of hostnames exist in DNS. I am already using the InetAddress method to return the IP's associated with these Hostnames. There is a problem though, the DNS server has entries for pc's that don't actually exist physically. Due to something such as the pc was removed or never installed. Is there a way to determine when the last time that pc was pingable?

That way I can trim my list of connectable pc's.
