Can't find DNS record!!

[mwilliamsess]

I can ping computername 125217 and get a reply. The IP it replies from is on another computer 125096. There are entries in DNS for 125096 but not for 125217. 125217 is not a computer on out network and it not listed in AD. There are no hosts file with entries to 125217, no entries in DNS, or WINS for this mystery computername? I have cleared the cache on both of our DNS servers and it is still picking up the same IP Address. I manually created an entry in DNS for 125217 and gave it a different IP. Tried to ping and it was looking for the IP I assigned in DNS. Then I deleted this record and tried to ping and it goes back to the same IP as before. I cannot get this out of DNS. I can't find where to delete it? Please help

Don't use numeric hostnames. If you must, then enclose them in quotes when you use them. Try:

ping "125217"
