IP address geocoder
===============
# Function
````
SELECT geocode_ip(Array['1.0.16.0', '::ffff:1.0.16.0'])
`````
# Creation steps
1. Create the `ip_address_locations` table
2. Obtain the file from http://geolite.maxmind.com/download/geoip/database/GeoLite2-City-CSV.zip
3. Uncompress it and upload the `GeoLite2-City-Blocks-IPv4.csv` file
4. Rename the uploaded table as `latest_ip_address_locations`
5. Run the `sql/build_data_table` script to update the table
# Tables
### ip_address_locations
This table, obtained from GeoLite and curated with `sql/build_data_table` contains a list of IP addresses and their location.
#### Table structure
````
Table "public.ip_address_locations"
Column | Type | Modifiers | Storage
----------------------+--------------------------+---------------------------------------------------------------------------+---------
network_start_ip | inet | | main
the_geom | geometry(Geometry,4326) | | main
cartodb_id | integer | not null default nextval('geolite2_city_blocks_cartodb_id_seq'::regclass) | plain
created_at | timestamp with time zone | not null default now() | plain
updated_at | timestamp with time zone | not null default now() | plain
the_geom_webmercator | geometry(Geometry,3857) | | main

# Testing
In order to test the data and the functions created under the script avaialble in this folder, you will need to run `bash test.sh` from `test/data` and `test/functions`.
# Known issues
* IPv6 addresses support?
# Historic:
* [08/10/2015]:
* Added response data types
* [14/07/2015]:
* Added tests
* [24/06/2015]:
* Update readme.md: Adds Known issues section
* Supervised function available in `geocoder.sql`
* [23/06/2015]:
* Updates `README.md`: adds testing and table structure sections. Updates creation steps
* Adding test structure for IP addresses geocoder
