NAME

SYNOPSIS

  use Geo::IP::PurePerl;

  my $gi = Geo::IP::PurePerl->new(GEOIP_STANDARD);

  # look up IP address '24.24.24.24'
  my $country = $gi->country_code_by_addr('24.24.24.24');
  $country = $gi->country_code_by_name('yahoo.com');
  # $country is equal to "US"

DESCRIPTION

This module can be used to automatically select the geographically closest mirror, to analyze your web server logs to determine the countries of your visiters, for credit card fraud detection, and for software export controls.

IP ADDRESS TO COUNTRY DATABASES

  http://www.maxmind.com/download/geoip/database/

This free database is similar to the database contained in IP::Country, as well as many paid databases. It uses ARIN, RIPE, APNIC, and LACNIC whois to obtain the IP->Country mappings.

If you require greater accuracy, MaxMind offers a paid database on a paid subscription basis from http://www.maxmind.com/app/country

CLASS METHODS

$gi = Geo::IP->new( [$flags] );

Constructs a new Geo::IP object with the default database located inside your system's datadir, typically /usr/local/share/GeoIP/GeoIP.dat.

Flags can be set to either GEOIP_STANDARD, or for faster performance (at a cost of using more memory), GEOIP_MEMORY_CACHE. The default flag is GEOIP_STANDARD (uses less memory, but runs slower).

$gi = Geo::IP->new( $database_filename );

Calling the "new" constructor in this fashion was was deprecated after version 0.26 in order to make the XS and pure perl interfaces more similar. Use the "open" constructor (below) if you need to specify a path. Eventually, this means of calling "new" will no longer be supported.

Flags can be set to either GEOIP_STANDARD, or for faster performance (at a cost of using more memory), GEOIP_MEMORY_CACHE.

$gi = Geo::IP->open( $database_filename, [$flags] );

Constructs a new Geo::IP object with the database located at $database_filename. The default flag is GEOIP_STANDARD (uses less memory, but runs slower).

OBJECT METHODS

$code = $gi->country_code_by_addr( $ipaddr );

Returns the ISO 3166 country code for an IP address.

$code = $gi->country_code_by_name( $ipname );

Returns the ISO 3166 country code for a hostname.

$code = $gi->country_code3_by_addr( $ipaddr );

Returns the 3 letter country code for an IP address.

$code = $gi->country_code3_by_name( $ipname );

Returns the 3 letter country code for a hostname.

$name = $gi->country_name_by_addr( $ipaddr );

Returns the full country name for an IP address.

$name = $gi->country_name_by_name( $ipname );

Returns the full country name for a hostname.

$info = $gi->database_info;

Returns database string, includes version, date, build number and copyright notice.

$old_charset = $gi->set_charset( $charset );

Set the charset for the city name - defaults to GEOIP_CHARSET_ISO_8859_1. To set UTF8, pass GEOIP_CHARSET_UTF8 to set_charset.

$charset = $gi->charset;

Gets the currently used charset.

$netmask = $gi->last_netmask;

Gets netmask of network block from last lookup.

$gi->netmask(12);

Sets netmask for the last lookup

my ( $from, $to ) = $gi->range_by_ip('24.24.24.24');

Returns the start and end of the current network block. The method tries to join several continous netblocks.

@data = $gi->get_city_record( $addr );

 Returns a array filled with information about the city.

  my ($country_code,$country_code3,$country_name,$region,$city,$postal_code,$latitude,$longitude,$metro_code,$area_code ) = $gi->get_city_record($addr);
    

$href = get_city_record_as_hash( $addr );

 Returns a hashref filled with information about the city.

  my $href = $gi->get_city_record_as_hash($addr);
    

The hash include the following keys: country_code, country_code3, country_name, region, city, postal_code, latitude, longitude, metro_code, area_code

$gi->isp_by_addr($addr)

 Returns the isp name for an ipaddress
    

$gi->isp_by_name($name)

 Returns the isp name for a hostname
    

$gi->org_by_addr($addr)
