HostIP for geolocation
The hostip.info geolocation database is free
and fairly accurate.
When I downloaded the bz2 version. It appears to be gzipped multiple times. I don't know why, but if you have trouble opening it trying using the `file` command to see what format it is in. Keep gunzipping it until your get ascii text. Here is what I had to do:
$ bunzip2 hostip_current.sql.bz2 $ mv hostip_current.sql hostip_current.sql.gz $ gunzip hostip_current.sql.gz $ mv hostip_current.sql hostip_current.sql.gz # yes, do it again $ gunzip hostip_current.sql.gz
I knew I was done when `file` gave me this results:
$ file hostip_current.sql hostip_current.sql: ASCII text, with very long line
Now, to actually use this thing here is what I to did. Create a database for hostip and load the data:
$ mysql -u root -p ROOT_PASSWORD -e "create database hostip;" $ mysql -u root -p ROOT_PASSWORD hostip < hostip_current.sql
That gave me a nice database. Each A block of an IP address is stored in a different table. It was pretty easy to write a Python script that would decode an IP address into (city, state, country, lat, lon).
