# NAME Robots::Validate - validate IP addresses are associated with known robots # VERSION version v0.1.1 # SYNOPSIS ```perl use Robots::Validate; my $rv = Robots::Validate->new; ... if ( $rs->validate( $ip, \%opts ) ) { ... } ``` # DESCRIPTION # ATTRIBUTES ## `resolver` This is the [Net::DNS::Resolver](https://metacpan.org/pod/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"](#validate) will die on a ["resolver"](#resolver) failure. By default it is false. # METHODS ## `validate` ```perl 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"](#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. # SEE ALSO - [Verifying Bingbot](https://www.bing.com/webmaster/help/how-to-verify-bingbot-3905dc26) - [Verifying Goodlebot](https://support.google.com/webmasters/answer/80553) - [How to check that a robot belongs to Yandex](https://yandex.com/support/webmaster/robot-workings/check-yandex-robots.html) # SOURCE The development version is on github at [https://github.com/robrwo/Robots-Validate](https://github.com/robrwo/Robots-Validate) and may be cloned from [git://github.com/robrwo/Robots-Validate.git](git://github.com/robrwo/Robots-Validate.git) # BUGS Please report any bugs or feature requests on the bugtracker website [https://github.com/robrwo/Robots-Validate/issues](https://github.com/robrwo/Robots-Validate/issues) When submitting a bug or request, please include a test-file or a patch to an existing test-file that illustrates the bug or desired feature. # AUTHOR Robert Rothenberg # COPYRIGHT AND LICENSE This software is Copyright (c) 2018 by Robert Rothenberg.
