reverse lookup/domain lookup in PHP

[Chris Kranz]

> Is it possible to reverse lookup (like here

[url]http://www.whatismyipaddress.com/reverse.asp[/url]) to find the domain with PHP? I
assume a DNS lookup requires an external server somewhere?

you can use exec or similar and to a reverse lookup like that... a
traceroute should cover it. please don't copy and paste my code, just giving
you an idea of what you'll do...

exec("traceroute ".$ip." > file.tmp")

then read the contents of file.tmp and you should be able to get the whole
of the traceroute. this brings up certain issues with speed of a traceroute
and run times of a script. also there may be a better way of doing this
other than piping the contents into a temporary file, but i've had issues
with reading what exec() outputs before (or whatever system call function
you'd like to use)

.... hope this helps a little

Sorry i don't know the script to get the reverse lookup.But i know site called whoisxy.com .
Here i found the reverse lookup tool.With the help of this you can know the number of the domains hosted on the single ip.
