IP::Country::MaxMind - Look up country by IP Address SYNOPSIS
use IP::Country::MaxMind; my $gi = IP::Country::MaxMind->new(GEOIP_STANDARD); # look up IP address '65.15.30.247' # returns undef if country is unallocated, or not defined in our database my $cc1 = $gi->inet_atocc('65.15.30.247'); my $cc2 = $gi->inet_atocc('yahoo.com'); DESCRIPTION
This module adapts the Geo::IP module to use the same interface as the IP::Country modules; thus allowing users to easily switch between using the two underlying databases. DATABASE UPDATES
Free monthly updates to the database are available from http://www.maxmind.com/download/geoip/database/ If you require greater accuracy, MaxMind offers a Premium database on a paid subscription basis. The author of this module is in no way associated with MaxMind. CLASS METHODS
$gi = IP::Country::MaxMind->new( $flags ); Constructs a new IP::Country::MaxMind 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. When using memory cache you can force a reload if the file is updated by setting GEOIP_CHECK_CACHE. $gi = IP::Country::MaxMind->open( $database_filename, $flags ); Constructs a new Geo::IP object with the database located at $database_filename. OBJECT METHODS
All object methods are designed to be used in an object-oriented fashion. $result = $object->foo_method($bar,$baz); Using the module in a procedural fashion (without the arrow syntax) won't work. $cc = $gi->inet_atocc(HOSTNAME) Takes a string giving the name of a host, and translates that to an two-letter country code. Takes arguments of both the 'rtfm.mit.edu' type and '18.181.0.24'. If the host name cannot be resolved, returns undef. If the resolved IP address is not contained within the database, returns undef. $cc = $gi->inet_ntocc(IP_ADDRESS) Takes a string (an opaque string as returned by Socket::inet_aton()) and translates it into a two-letter country code. If the IP address is not contained within the database, returns undef. $cc = $gi->db_time() Returns zero. For compatibility only. COPYRIGHT

Geo::IP - Look up location and network information by IP Address SYNOPSIS
use Geo::IP; my $gi = Geo::IP->new(GEOIP_MEMORY_CACHE); # look up IP address '24.24.24.24' # returns undef if country is unallocated, or not defined in our database my $country = $gi->country_code_by_addr('24.24.24.24'); $country = $gi->country_code_by_name('yahoo.com'); # $country is equal to "US" use Geo::IP; my $gi = Geo::IP->open("/usr/local/share/GeoIP/GeoIPCity.dat", GEOIP_STANDARD); my $record = $gi->record_by_addr('24.24.24.24'); print $record->country_code, $record->country_code3, $record->country_name, $record->region, $record->region_name, $record->city, $record->postal_code, $record->latitude, $record->longitude, $record->time_zone, $record->area_code, $record->continent_code, $record->metro_code; # the IPv6 support is currently only avail if you use the CAPI which is much # faster anyway. ie: print Geo::IP->api equals to 'CAPI' use Socket; use Socket6; use Geo::IP; my $g = Geo::IP->open('/usr/local/share/GeoIP/GeoIPv6.dat') or die; print $g->country_code_by_ipnum_v6(inet_pton AF_INET6, '::24.24.24.24'); print $g->country_code_by_addr_v6('2a02:e88::'); DESCRIPTION
This module uses a file based database. This database simply contains IP blocks as keys, and countries as values. This database should be more complete and accurate than reverse DNS lookups. This module can be used to automatically select the geographically closest mirror, to analyze your web server logs to determine the countries of your visitors, for credit card fraud detection, and for software export controls. IP ADDRESS TO COUNTRY DATABASES
Free monthly updates to the database are available from 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 database on a paid subscription basis. Also included with this is a service that updates your database automatically each month, by running a program called geoipupdate included with the C API from a cronjob. For more details on the differences between the free and paid databases, see: http://www.maxmind.com/app/geoip_country Do not miss the city database, described in Geo::IP::Record Make sure to use the geolite-mirror-simple.pl script from the example directory to stay current with the databases. BENCHMARK the lookups are fast. This is my laptop ( examples/benchmark.pl ): Benchmark: running city_mem, city_std, country_mem, country_std, country_v6_mem, country_v6_std, isp_mem, isp_std for at least 10 CPU seconds... city_mem: 10.3121 wallclock secs (10.30 usr + 0.01 sys = 10.31 CPU) @ 387271.48/s (n=3992769) city_std: 10.0658 wallclock secs ( 2.86 usr + 7.17 sys = 10.03 CPU) @ 54392.62/s (n=545558) country_mem: 10.1772 wallclock secs (10.16 usr + 0.00 sys = 10.16 CPU) @ 1077507.97/s (n=10947481) country_std: 10.1432 wallclock secs ( 2.30 usr + 7.85 sys = 10.15 CPU) @ 83629.56/s (n=848840) country_v6_mem: 10.2579 wallclock secs (10.25 usr + -0.00 sys = 10.25 CPU) @ 365997.37/s (n=3751473) country_v6_std: 10.8541 wallclock secs ( 1.77 usr + 9.07 sys = 10.84 CPU) @ 10110.42/s (n=109597) isp_mem: 10.147 wallclock secs (10.13 usr + 0.01 sys = 10.14 CPU) @ 590109.66/s (n=5983712) isp_std: 10.0484 wallclock secs ( 2.71 usr + 7.33 sys = 10.04 CPU) @ 73186.35/s (n=734791) 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. When using memory cache you can force a reload if the file is updated by setting GEOIP_CHECK_CACHE. GEOIP_INDEX_CACHE caches the most frequently accessed index portion of the database, resulting in faster lookups than GEOIP_STANDARD, but less memory usage than GEOIP_MEMORY_CACHE - useful for larger databases such as GeoIP Organization and GeoIP City. Note, for GeoIP Country, Region and Netspeed databases, GEOIP_INDEX_CACHE is equivalent to GEOIP_MEMORY_CACHE To combine flags, use the bitwise OR operator, |. For example, to cache the database in memory, but check for an updated GeoIP.dat file, use: Geo::IP->new( GEOIP_MEMORY_CACHE | GEOIP_CHECK_CACHE. ); $gi = Geo::IP->open( $database_filename, $flags ); Constructs a new Geo::IP object with the database located at $database_filename. $gi = Geo::IP->open_type( $database_type, $flags ); Constructs a new Geo::IP object with the $database_type database located in the standard location. For example $gi = Geo::IP->open_type( GEOIP_CITY_EDITION_REV1 , GEOIP_STANDARD ); opens the database file in the standard location for GeoIP City, typically /usr/local/share/GeoIP/GeoIPCity.dat. 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( $hostname ); 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( $hostname ); 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( $hostname ); Returns the full country name for a hostname. $r = $gi->record_by_addr( $ipaddr ); Returns a Geo::IP::Record object containing city location for an IP address. $r = $gi->record_by_name( $hostname ); Returns a Geo::IP::Record object containing city location for a hostname. $org = $gi->org_by_addr( $ipaddr ); deprecated use "name_by_addr" instead.
