Hi there,

If this question is already answer, please help to find it. Is there Perl or CGI program that can trace IP address to its ISP?

Please help!

Thanks

Yes. Look into "traceroute". It's a unix command which can do what you want.

And here's a good example.... Though the CGI script is written in C.

Hit places like http://www.HotScripts.com and http://www.FreePerlCode.com -- you'll find scripts for this.
