Hi! Presuming that by "basic info" you mean the hostname associated with that IP, you can use gethostbyaddr function, or the Net::DNS module. If, instead, you want to know where the host with that IP address is located, you can try the module Net::Traceroute or Net::Traceroute::PurePerl (the last one is in pure Perl, it doesn't use XS). Even when you trace the host, it might be difficult for you to know where it's phisically located: you'll either need a visual traceroute, or a whois query for that IP address on the ARIN database, to know that; Net::Whois should be helpful in this task.

Do you mean infromation about who is authoritative for the address?? If so, Net::Whois::IP will give you that info `#!/usr/bin/perl -w use strict; use Net::Whois::IP qw(whoisip_query); my $ip = "206.157.230.50"; my ($response,$array_of_responses) = whoisip_query($ip); foreach my $key (keys%$response) { print "$key - ", $response->{$key}, "\n" }` [download]	[reply] [d/l]

Not sure exactly what you are looking for, but you can get more information from an IP address with Net::DNS. `getbyaddr` might also be of use.	[reply] [d/l]

another alternative is to use javascript to retrieve user information associated with the ip's machine then send that to a perl script where the information is manipulated. use the <img> tag in a web page to capture the information and send it to a perl script. You will probably want the perl script to return a 1x1 pixel blank image so it works properly. `<SCRIPT language=javascript> //<!--var x; x=""; x+="<img src='http://yoursite/cgi-bin/capture.cgi?page="; x+=escape(location.pathname)+"&ref="+escape(document.referrer)+"&ua="+ +escape(navigator.userAgent)+"&plat="; x+=escape(navigator.platform)+"&cooks="+escape(navigator.cookieEnabled +)+"&cpu="; x+=escape(navigator.cpuClass)+"&java="+escape(navigator.javaEnabled()) ++"'>"; document.write(x); //--> </script>` [download] this will capture several machine specific details that can be parsed by your perl program. Then in the capture.cgi you will want to simple use the ENV var to retrieve the ip address as you probably were.	[reply] [d/l]
