DNS resolves to 2 different domain names?

[irbk]

I am researching some problems with our e-mail system this morning, and I noticed something that seemed quite wrong with our DNS. If I go to a CMD prompt and type

ping -a 64.224.190.175

I get a return of

Pinging singlesdining.com [64.224.190.175] with 32 bytes of data: ..... blah blah blah

Singlesdining.com is NOT my domain name, however, some how with a ping -a, singlesdining.com is what is resolving. Now if you ping my domain name

ping tnainc.com

I get

Pinging tnainc.com [64.224.190.175] with 32.....

I don't understand how 2 different domain names are resolving to the same IP. DNS is a whole lot of black magic to me, so I'm not sure if this is wrong or if a DNS setting is screwed up somewhere. My DNS and corp website are hosted by web.com, but it doesn't seem like this singlesdining.com is hosted by web.com, so I'm very confused as to why this is happening. Please let me know if this is wrong, and if it is wrong, what I'm going to need to tell web.com to change when I call them.

Thanks in advance!

Yes, it is wrong. Ask them to check your A and DNS records to make sure they have the correct name. Should be an easy fix for them. Here is a whois report for you:

Here is a link that helps explain some of the records used in DNS:

Actually seeing that your website is hosted, they use virtual services on the same box. Thus your site uses the same ip address as the other sites on the box and apache redirects based on the requested url.

You should be looking at your mx record, and not your

http://WWW record.

tnainc.com. NS IN 86400 a.ns.interland.net.
tnainc.com. NS IN 86400 b.ns.interland.net.
tnainc.com. NS IN 86400 c.ns.interland.net.
tnainc.com. MX IN 900 mail.tnainc.com. [Preference = 5]
tnainc.com. A IN 1800 64.224.190.175
a.ns.interland.net. A IN 86400 64.226.28.33

Thanks for your help! I was able to get web.com to update the reverse PTR record for my domain and all resolves well now.
