Finding all sites hosted on a specific IP address
Afternoon/Evening,
I know it's possible to have multiple websites running from one IP address, each having distinctly different domain names. Is it possible for someone to search that IP address and locate all the sites that are hosted on it? If so, how? |
www.iptools.com works for some websites.
|
No. You may be able to do a zone transfer against their DNS server, but only a badly configured DNS server will allow you to AXFR.
|
Thanks chaps, didn't think it would be possible, and it's a good thing that it's not really.
|
If it were possible, there would be a number of embarrassed ISPs out there...
|
I've just re-read the question, and totally got the wrong end of the stick! lol

You could find out how few/many sites they have hosted...
Some hosts will say we dont host more than 100 sites per shared server... Some will say they are bigger than they are. You could also find out a hosting companies customers and spam all the other sites saying 'we are cheaper than this person' cos they'll know their hosting plans.... To name a few ideas.... |
Most of that information (apart from the hard sell which I didn't think of) is useless unless you also know what kind of hardware is running or they're advertising it as "N virtuals per physical host" (which is actually a worthless thing to say, since there's nothing wrong with mass vhosting, more vhosts != less performance, mod_vhost_alias for Apache is just for that), and customers pay for bandwidth. Security could be a problem though, if you can break through someone's poorly written code, gain shell access, to get at another site's info.

Then any information that could be gleaned from a balanced setup would be incorrect, but the person doing the scan wouldn't know that.
Good job this isn't technically possible anwyay :) |
The question was "Is it possible for someone to search that IP address and locate all the sites that are hosted on it? If so, how?"
thats all... :rolleyes: ;) |
OK: No.
