We just set up a new server (svr1) and I'm pretty sure we haven't assigned a public IP for it yet. But when I ping it (svr1.mydomain.com) against our DNS server, the host was resolved into an ip 184.108.40.206 that I'm sure not our IP. I was so surpised since I expected to see something like "Can not resolve host ..." etc.
Then I felt it just makes no sense so I kept pinging with some non-sense names and found all were resolved to the above same ip address 220.127.116.11, instead of "Can not resolve host".
Then when I got into my DNS server / Cached Lookups zone, under mydomain, I saw all server and non-sense names i ping earlier and all are with the following two entries:
Name Server (NS) wsc1.jomax.net
Name Server (NS) wsc2.jomax.net
Why are all non-sense host names resolved, and to the same IP address by jomax.net? Is my DNS corrupt? Please help.
