The hostip.info geolocation database is free
and accurate. You can use this to turn an IP address into a geographic coordinates. It also includes city, state, and country information.
When I downloaded the bz2 version it appeared to be gzipped multiple times. I don't know why that is, 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 data 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, country_code lat, lon}.
#!/usr/bin/env python # hostipgeo.py # HostIP.info geolocation lookup. # Run this script with an IP address as an argument and it will return # the following information: {city, state, country, country_code lat, lon}. # Noah Spurrier 2007 import MySQLdb import os, sys, urllib ip = sys.argv[1].split('.') con = MySQLdb.Connect(host="127.0.0.1", port=3306, user="root", passwd="", db="hostip") #, unix_socket='/var/lib/mysql/mysql.sock') cursor = con.cursor() table_a = "ip4_" + ip[0] net_b = ip[1] net_c = ip[2] sql = """SELECT cityByCountry.name as city, cityByCountry.state as state, countries.name as country, countries.code as country_code, cityByCountry.lat as lat, cityByCountry.lng as lon FROM %(table_a)s, countries, cityByCountry WHERE %(table_a)s.city=cityByCountry.city AND %(table_a)s.country=cityByCountry.country AND %(table_a)s.country=countries.id AND b=%(net_b)s AND c=%(net_c)s;""" sql = sql % locals() if cursor.execute(sql) == 0: print "That IP address was not found in the database." sys.exit(1) con.close() results = list(cursor.fetchall()[0]) results[0] = urllib.unquote(results[0]) keys = ['city','state','county','country_code','lat','lon'] results_dict = dict(zip(keys, results)) for key in keys: print "%12s: %s" %(key, results_dict[key]) sys.exit(0)
Running this script on the IP address 69.80.208.1 gives the following:
$ ./hostipgeo.py 69.80.208.1 city: San Francisco, CA state: California county: UNITED STATES country_code: US lat: 37.8133 lon: -122.50
