NAME

geoip - A Tcl extension for geographic or organisational lookup of IP addresses and hostnames.

SYNOPSIS

geoip open [-type TYPE ] [-flags FLAG ]
geoip open [-file PATH ] [-flags FLAG ]
geoip [COMMAND]
geoip [QUERY] arg1

DESCRIPTION

This Tcl extension encapsulates most of GeoIP C API functions into tcl commands.

OPEN OPTIONS

open takes either a file path and a set of flags, or a type and a set of flags. Supported types and flags are described below.

TYPE: Looks under the standard installation share directory, eg /usr/local/share/GeoIP/ for a GeoIP database according to type.
PATH: Absolute/relative path to GeoIP database.
FLAG: Flags seperated by ':', eg memory_cache:memory_check

COMMAND

Individual singular commands can be one of:

close: Close the currently open database.
db_info: Get information about the current database.
db_edition: Returns edition of opened database.
db_avail: Test the availability of databases in your system in known locations. e.g db_avail country_edition

QUERY

Commands that query the database. All commands return N/A if a result cannot be found. If none already open, a command will attempt to open a suitable database. country commands will open a country_edition database. region commands will open a region_edition_rev1 one. name commands will open an org_edition one, and the record_edition will open a city_edition_rev1 database. The commands are:

country_code_by_addr: Takes an IP address and returns the ISO-3166-1 Alpha-2 code of the country.
country_code3_by_addr: Takes an IP address and returns the ISO-3166-1 Alpha-3 code the country.
country_code_by_name: Takes a hostname and returns the ISO-3166-1 Alpha-2 code the country.
country_code3_by_name: Takes a hostname and returns the ISO-3166-1 Alpha-3 code the country.
country_name_by_addr: Takes an IP address and returns the country name.
country_name_by_name: Takes a hostname and returns the country name.
name_by_addr: Takes an IP address and returns the organisation name (or ISP/ASnum according to the opened database)
name_by_name: Takes a hostname and returns the organisation name.
region_by_addr: Takes an IP address and returns these region attributes as in an associative array: country, region
region_by_name: Takes a hostname and returns the region attributes.
record_by_addr: Takes an IP address and returns these record attributes as in an associative array: code, code3, region, country, city, postcode, latitude, longitude, dma(dma code), and area (area code)
record_by_name: Takes a hostname and returns the record attributes.

TYPES

Relevant types of databases are: country_edition, org_edition, isp_edition, city_edition_rev1, region_edition_rev1, geoip_asnum_edition. "open -type" will accept their unambiguous abbreviations.

FLAGS

Valid flags are: standard, memory_cache, check_cache, index_cache.
