Is there a console command that takes an IP address as an input and shows its geographical information like city, country, ISP, etc.?

The command is the easy part, the difficult part is having access to a database.

For example, Ubuntu has a free database with a command line query tool (geoiplookup) in the geoip-bin Install geoip-bin package. But it only shows country information, and uses a static (hence out-of-date) database. This tool can also query the MaxMind GeoIP database, if you have a subscription there.

There are various GeoIP databases that you can look up. They're generally meant to be viewed through a web browser, but you can look for a scraping script. For example, here's a ruby script to retrieve data from the MaxMind database. Note that scraping may be against the database's terms of service.

just used the ubuntu geoiplookup and it is good enough. – BuZain Feb 15 '11 at 17:57
CentOS# yum install GeoIP – zmonteca Jul 1 '14 at 22:50

This trick is even nicer and doesn't require any external packages:

curl ipinfo.io/

In case ipinfo.io gets offline someday, ifconfig.me provides a similar service (plus a REST-like API). But ifonfo.io seems much faster. – cedbeu Mar 5 '15 at 15:48
Meh, doesn't allow hostnames... – erm3nda Mar 11 at 4:47
$ host yourdomain.com | cut -d ' ' -f 4 | curl ipinfo.io/$1 – zmonteca Mar 22 at 15:57

Here's another great option. Instructions here: http://kbeezie.com/geoiplookup-command-line/

For example, on Centos:

$ sudo yum install GeoIP GeoIP-data
$ geoiplookup

Works perfectly.

And of course, you can always set this up as a cron:

$ /usr/bin/geoipupdate
