ip resolves wrong hostname??

ok I know there was a big huge thread regarding something similar - or maybe the same thing...but I think this is a little different...

when I run a check on my servers IP at

http://centralops.net/co/DomainDossier.vbs.asp

I get: keystone.rsvault.com

BUT, at that same site - if I check on

rsvault.com
keystone.rsvault.com
ns1.rsvault.com
ns2.rsvault.com

I do NOT get my IP.

So does this mean something is whacky on my server from the day I got it?

I'm thoroughly confused...

 

ummm well see that's the problem

that's not my domain. there's no entry for it on my server.

I run doorhost.net and the server hostname is dh2.doorhost.net

not keystone.rsvault.com
