I'm not the network admin, so bear with me please.

Is there a way to find out which DNS server is responding to a TRACERT?

When we type


the wrong domain name comes back:

Tracing route to []

It should say:

Tracing route to []

When we look at the DNS records of, they point to the correct IP address, not to Same for domain-A. The IP addresses look correct.

How do we troubleshoot this? How do we find out where is being incorrectly linked to domain-A?

tracert will give you the PTR, the reverse DNS entry for the IP, not the hostname you supplied on commandline.

So, maybe AND both resolve to (A-Record) and the reverse DNS entry is set to (PTR-Record)

Thanks -- it was the PTR record that had the incorrect domain name. – Tim Jun 29 '11 at 14:22

I can't tell from your question whether you are asking a question to learn or to resolve a particular problem. If the latter, then it might help to describe the problem, since it is very probable that this info, whilst maybe confusing, is irrelevant to the problem.

The name reported by a tracert is (as others have already said) the reverse dns entry (or one of the reverse dns entries) for that IP address is not related to a domain name. (For example, try pinging and then do a tracert to that IP address and you probably won't get any mention of google)

How do we find out where is being incorrectly linked to domain-A?

The reverse DNS entries are controlled by whoever owns the IP address. This is usually an ISP. In particular it is not controlled by whoever owns the website/mail server (etc) that happens to use that IP Address.

Also, if (as you say) the DNS records for do not point to, then why would you want the tracert to to refer to

I was trying to find out why our VPN went down (network admin on vacation). I learned the PTR record for the IP address associated with domain-A had the wrong domain name; however, learned also that the PTR record is only of consequence to a mail server, if any, and wouldn't be responsible for a VPN issue.
