Remove DNS lookup

[David Wall]

Is there a class that can do a reverse DNS lookup, giving me the hostname
that matches a given IP address?  I'm able to retrieve the IP address of an
HTTP request just fine using request.getRemoteAddr() (and getRemoteHost()
returns the same IP address dotted numbers), but the java.net package
doesn't seem to have
anything that returns a name based on an IP address, unless I'm just
misreading InetAddress...
