NAME

Robots::Validate - Validate that IP addresses are associated with known robots

VERSION

version v0.1.5

SYNOPSIS

use Robots::Validate;

my $rv = Robots::Validate->new;

...

if ( $rs->validate( $ip, \%opts ) ) { ...  }

DESCRIPTION

ATTRIBUTES

resolver

This is the Net::DNS::Resolver used for DNS lookups.

robots

This is an array reference of rules with information about robots. Each item is a hash reference with the following keys:

  • name

    The name of the robot.

  • agent

    A regular expression for matching against user agent names.

  • domain

    A regular expression for matching against the hostname.

die_on_error

When true, "validate" will die on a "resolver" failure.

By default it is false.

METHODS

validate

my $result = $rv->validate( $ip, \%opts );

This method attempts to validate that an IP address belongs to a known robot by first looking up the hostname that corresponds to the IP address, and then validating that the hostname resolves to that IP address.

If this succeeds, it then checks if the hostname is associated with a known web robot.

If that succeeds, it returns a copy of the matched rule from "robots".

You can specify the following %opts:

  • agent

    This is the user-agent string. If it does not match, then the DNS lookkups will not be performed.

    It is optional.

KNOWN ISSUES

Limitations

The current module can only be used for systems that consistently support reverse DNS lookups. This means that it cannot be used to validate some robots from Facebook or Twitter.
