How to create a custom Maxmind database with PRIVATE IPs address.
I need something like this Customizing Maxmind DB.
I tried to following this Building Your Own MMDB Database for Fun and Profit . So I changed the PERL script to the following:
#!/usr/bin/env perl
use strict;
use warnings;
use feature qw( say );
use MaxMind::DB::Writer::Tree;
use Net::Works::Network;
my $filename = 'users.mmdb';
# Your top level data structure will always be a map (hash). The MMDB format
# is strongly typed. Describe your data types here.
# See https://metacpan.org/pod/MaxMind::DB::Writer::Tree#DATA-TYPES
my %types = (
latitude => 'uint32',
longitude => 'uint32',
city => 'utf8_string',
country => 'utf_string',
);
my $tree = MaxMind::DB::Writer::Tree->new(
# "database_type" is some arbitrary string describing the database. At
# MaxMind we use strings like 'GeoIP2-City', 'GeoIP2-Country', etc.
database_type => 'My-IP-Data',
# "description" is a hashref where the keys are language names and the
# values are descriptions of the database in that language.
description =>
{ en => 'My database of IP data', fr => q{Mon Data d'IP}, },
# "ip_version" can be either 4 or 6
ip_version => 4,
# add a callback to validate data going in to the database
map_key_type_callback => sub { $types{ $_[0] } },
# "record_size" is the record size in bits. Either 24, 28 or 32.
record_size => 24,
);
my %address_for_employee = (
'10.1.0.0/16' => {
latitude => -12.9608,
longitude => 40.5078,
city => 'Maputo',
country => 'Mozambique',
},
'10.2.0.0/16' => {
latitude => -25.0519,
longitude => 33.6442,
city => 'Gaza',
country => 'Mozambique',
},
);
for my $address ( keys %address_for_employee ) {
# Create one network and insert it into our database
my $network = Net::Works::Network->new_from_string( string => $address );
$tree->insert_network( $network, $address_for_employee{$address} );
}
# Write the database to disk.
open my $fh, '>:raw', $filename;
$tree->write_tree( $fh );
close $fh;
say "$filename has now been created";
But no luck. Now Im getting the following error : Iteration is not currently allowed in trees with no nodes. Record type: empty at /usr/local/lib/perl/5.14.2/MaxMind/DB/Writer/Tree.pm line 292.
Can anybody help me creating a GEOIP2 DB with private ip address?
