Hi All,

I wanted to know whether anyone of you knows any "IP Address -> ISP,
Country" database.

I am talking of developing a service like
http://aruljohn.com/track.html which will require such a database.

There is one at http://www.ip2nation.com/ . But it only provides the
IP->Country mapping.

I'll be happy if someone of you can post a link to such a FREE database
online.

It cannot be done in the general case. If I'm visiting a different
country and dial up to my system at work, then the IP address I get
is one from work, not one that reflects the country I happen to be
calling from.

There are a number of services that offer semi-reasonable approximations.

That system doesn't return information about the ISP: it returns
information about who the address block is registered to.
For example, if I enter one of my work IP addresses, then I
get information about the name of our organization, since that
particular block is registered to us. But that doesn't say anything
about who our ISP is. I don't even -know- who our ISP is these days,
as the local consortium contracts out ISP service on multiyear bids,
with no visible effect on our service.
