This only works with forward lookups (not IP numbers).
Perfom a different type of test on the same domain: NSLookup Gateway - queries 15 major US nameservers and several foreign nameservers. Custom NSLookup Gateway - do your own lookup off of the DNS server that you want. MXLookup Gateway - same as above, but it looks up the MX (Mail Exchanger) for hosts. RBL Lookup - checks to see if a host/IP # is on any Realtime Blackhole Lists. Open Relay Tester Tool - attempts to relay a single message through a remote mail server. Whois Lookup - checks domain to see if its registered. And if so, it provides info on it. RWhois Lookup - Referral Whois, similar to whois but with more info Traceroute Tool - traces the route to said host and sends 10 packets and reports the results. Long(er) Traceroute Tool - traces the route to said host and sends 50 packets and reports the results.
