Looking up all domains owned by a particular company

Have some information, but can't do reverse lookup with IP

[Christopher C]

Hello,

I was hoping to find out all domains owned by a particular company. The registrant for the domains that I know of are identical but administrative contacts, dns servers, ip addresses, and so forth are not the same.

It does also seem that the domains were registered through Network Solutions Inc.

Could someone please tell me is there a way I can search out additional names owned by this same company?

Thanks,
Chris

Likewise is there also a tool that you can use to search based on dns servers... therefore where webmasters are a little more cunning to disguise their names, their server will give them away!

You could try: whois. sc
It lists other websites a server hosts and lots of other interesting info.

Try webhosting.info
Gives a list of domains that uses the same dns (This is almost equal to sites hosted on a server)

No webhosting.info's data is not accurate enough to rely on for this kind of thing. The number of domains hosted on a nameserver is rarely equal to the number of websites hosted. The only way that you can reliably do this is by working upwards from the domain as the starting point. The webhosting.info process works down from the nameserver and is very error prone.

Jmcc, could you explain this a little more please?

What I'm faced with right now is that:
1) nameservers do not match
2) ip addresses do not match
3) potentially different registrars

So far, the only thing I've found for certain is that they are all registered to the same registrant (to the letter).

All I can think of is to get in contact with ICANN directly and see if they can get me the information. At least this would get me the .com, .net, and .org.

I can do it, if interested sticky.
