Reverse IP Lookup (for free)

Is there a way to see all COM, NET, ORG, INFO, BIZ, and US domains on any IP address totaly for free with no limit to 3 domains at a website or with a tool that runs on Windows 9x (98/SE, ME)?

Perhaps the tool nslookup (which comes with Windows) is what you are looking for.

Open a command prompt: Start > Run > 'cmd'
Type 'nslookup 1.2.3.4', substituting 1.2.3.4 with the IP you wish to reverse lookup.

If you're talking about something like what »www.whois.sc has, no, I don't know of a free service.

Whois.sc allows you to see three domains for free, and requires a "Silver Membership" to see all of them.

That site doesn't appear to work.

It shows 'some' of the hosts, but not even close to all of them.

I have 21 sites on one ip and it only shows 4

It's doing as good a job as physically possible.

Going from a single IP address to the canonical inverse name is a deterministic process (via in-addr.arpa), but that's not what these guys are doing.

They are showing A records that point to the given IP, and the only deterministic way to do this is to look in every zone on the internet. That's not really possible.

Instead, they just spider the web and look up www links as they come across them, and keep track of which records point to which IP addresses. The database accretes gradually, showing the partial coverage you have seen. But it's just not possible to find "all" the data in any trivial step.

I realize that there is no perfect solution to this problem as there is no real way to get a root nameserver to dump all A records that evaluate to a certain ip. I guess i just have a mindset that if you cannot do a reasonable job then don't do it at all.

whois.sc is able to find 12 sites on the same ip, which still isn't the best, but they also give other additional info on the same page.

I guess I have the mindset that an imperfect solution to an unsolvable problem is better than no solution at all.

I agree with you there, but their site doesn't seem to realize it is an imperfect solution.

Just curious. Do all 21 domains point to the same IP address when you do a reverse lookup on them?

I have a web hosting account that has two sites and there are five domains among the two sites plus two parked domains pointing to one of the sites, making that seven domain names. But the Webhosting.info tool only shows the five fomains that actually point to the web sites, not the parked ones. Are your 21 domains actually pointed to a real web server and not parked somewhere else and redirecting?

Thanks for the explanation - I always wondered how they did that. And I learned what the word 'accrete' means

With DNS, one can create any number of A records. However, PTR records are unique. Therefore, while you might find 21 A records that point to a single, common IP, you will only find one PTR that maps an IP to a hostname (if you're lucky: even still, a lot of sites don't bother to reverse map addresses).

All 21 domains have an A record pointing to the IP of the server, and there is an apache vhost (sometimes a serveralias) for each one of them.

Oddly enough, it appears that the whois page shows all of the domains attached to a specific vhost and none of the other ones. Very odd.

And just some more info relating to nixen See Profile's comment, the ip does have a PTR record (i have reverse dns authority over the subnet) and the whois site does not show the domain that is in the ptr record. Go figure.

Wrong answer. cmd and nslookup are only found NT based systems (Windows NT 3.5, 4.0, Windows 2000, XP).

I used Start >> Run >> 'Command.com'
Typed in 'nslookup 1.2.3.4', substituting 1.2.3.4 with the IP I wished to reverse, I have BIND-LE (software from »ntcanuck.com/ ), lookup. But it still does not answer my question. But I thank you for trying.

I also thank everyone else for the answers that they provided.

Anyone using a non NT shell windows shouldn't be allowed on the internet.
