NAME

       GeoIP2::Database::Reader - Perl API for GeoIP2 databases

VERSION

       version 2.006002

SYNOPSIS

         use 5.008;

         use GeoIP2::Database::Reader;

         my $reader = GeoIP2::Database::Reader->new(
             file    => '/path/to/database',  # e.g. /home/maxmind/db/GeoIP2-Country.mmdb
             locales => [ 'en', 'de', ]
         );

         my $city = $reader->city( ip => '24.24.24.24' );
         my $country = $city->country();
         print $country->iso_code(), "\n";

DESCRIPTION

       This class provides a reader API for all GeoIP2 databases. Each method returns a different
       model class.

       If the database does not return a particular piece of data for an IP address, the
       associated attribute is not populated.

USAGE

       The basic API for this class is the same for all database types.  First you create a
       database reader object with your "file" and "locale" params.  Then you call the method
       corresponding to your database type, passing it the IP address you want to look up.

       If the request succeeds, the method call will return a model class for the method point
       you called.

       If the database cannot be read, the reader class throws an exception.

IP GEOLOCATION USAGE

       IP geolocation is inherently imprecise. Locations are often near the center of the
       population. Any location provided by a GeoIP2 database should not be used to identify a
       particular address or household.

CONSTRUCTOR

       This class has a single constructor method:

   GeoIP2::Database::Reader->new()
       This method creates a new object. It accepts the following arguments:

       •   file

           This is the path to the GeoIP2 database which you'd like to query. The path should
           include the filename.

       •   locales

           This is an array reference where each value is a string indicating a locale.  This
           argument will be passed on to record classes to use when their "name()" methods are
           called.

           The order of the locales is significant. When a record class has multiple names
           (country, city, etc.), its "name()" method will look at each element of this array ref
           and return the first locale for which it has a name.

           Note that the only locale which is always present in the GeoIP2 data in "en".  If you
           do not include this locale, the "name()" method may end up returning "undef" even when
           the record in question has an English name.

           Currently, the valid list of locale codes is:

           •       de - German

           •       en - English

                   English names may still include accented characters if that is the accepted
                   spelling in English. In other words, English does not mean ASCII.

           •       es - Spanish

           •       fr - French

           •       ja - Japanese

           •       pt-BR - Brazilian Portuguese

           •       ru - Russian

           •       zh-CN - simplified Chinese

           Passing any other locale code will result in an error.

           The default value for this argument is "['en']".

REQUEST METHODS

       All of the request methods accept a single argument:

       •   ip

           This must be a valid IPv4 or IPv6 address. This is the address that you want to look
           up using the GeoIP2 web service.

           Unlike the web service client class, you cannot pass the string "me" as your ip
           address.

   $reader->asn()
       This method returns a GeoIP2::Model::ASN object.

   $reader->connection_type()
       This method returns a GeoIP2::Model::ConnectionType object.

   $reader->country()
       This method returns a GeoIP2::Model::Country object.

   $reader->city()
       This method returns a GeoIP2::Model::City object.

   $reader->domain()
       This method returns a GeoIP2::Model::Domain object.

   $reader->isp()
       This method returns a GeoIP2::Model::ISP object.

   $reader->enterprise()
       This method returns a GeoIP2::Model::Enterprise object.

   $reader->anonymous_ip()
       This method returns a GeoIP2::Model::AnonymousIP object.

OTHER METHODS

   $reader->metadata()
       This method returns a MaxMind::DB::Metadata object containing information about the
       database.

EXCEPTIONS

       In the case of a fatal error, the reader will throw a GeoIP2::Error::Generic or
       GeoIP2::Error::IPAddressNotFound exception object.

       This error class has an "$error->message()" method and overload stringification to show
       that message. This means that if you don't explicitly catch errors they will ultimately be
       sent to "STDERR" with some sort of (hopefully) useful error message.

WHAT DATA IS RETURNED?

       While many of the databases return the same basic records, the attributes which can be
       populated vary between model classes. In addition, while a database may offer a particular
       piece of data, MaxMind does not always have every piece of data for any given IP address.

       Because of these factors, it is possible for any model class to return a record where some
       or all of the attributes are unpopulated.

       See <http://dev.maxmind.com/geoip/geoip2/web-services> for details on what data each end
       point may return.

       Every record class attribute has a corresponding predicate method so you can check to see
       if the attribute is set.
