220.127.116.11 resolves to dns0.optus.net.au here in South Aus
(the server name is actually ns1.optus.net.au)
[MOD: I got that from other means, not a ping]
Name servers typically do not reply to pings with their domain names.
Also pinging an non-name server generally only gets you the servers gateway name, for example
try "ping www.themercury.com.au
or better "ping www.tasracing.com.au
In the latter case you should get something like
(18.104.22.168) 56(84) bytes of data.
64 bytes from fogell.ldmfoundry.com (22.214.171.124): icmp_req=1 ttl=49 time=26.8 ms

64 bytes from fogell.ldmfoundry.com (188.8.131.52): icmp_req=3 ttl=49 time=26.8 ms
and I happen to know that fogdell.ldmfoundry.com is the hosting service for TasRacing. So the result doesn't really provide a great deal of information!
Merry christmas, have a Mercury (cider) for me!
