DESCRIPTION ^

POE::Component::IRC::Plugin::QueryDNS is a POE::Component::IRC plugin that provides DNS query facilities to the channels it occupies and via private messaging.

It uses POE::Component::Client::DNS to do non-blocking DNS queries. By default the plugin attempts to use POE::Component::IRC's internal PoCo-Client-DNS resolver object, but will spawn its own copy. You can supply your own resolver object via the constructor.

CONSTRUCTOR ^

new

Creates a new plugin object. Takes some optional parameter:

  'command', define the command that will trigger DNS queries, default is 'dns';
  'privmsg', set to a true value to specify that the bot should reply with PRIVMSG instead of
             NOTICE to privmsgs that it receives.
  'resolver', specify a POE::Component::Client::DNS object that the plugin should use,
              the default is to try and use POE::Component::IRC's resolver;

IRC USAGE ^

The bot replies to requests in the following form, when addressed:

  dns <query> <optional_type>

Of course, if you changed the command in the constructor it will be something different to dns.

query maybe a hostname, a zone, an IP address, anything that you want to query DNS for.

type can be A, PTR, CNAME, NS, MX, TXT, AAAA, SRV or SOA. If it isn't specified the default is A unless the query is an IP address in which case the default is PTR.

Some examples:

   # No type, defaults to 'A'
   < you> bot: dns www.perl.org
   < bot> www.perl.org [ CNAME=x3.develooper.com. A=63.251.223.163 ]

   # No type, defaults to 'PTR' because the query is an IP address
   < you> bot: dns 63.251.223.163
   < bot> 63.251.223.163 [ PTR=x3.develooper.com. ]

   # Specify a type of 'MX'
   < you> bot: dns perl.org mx
   < bot> perl.org [ MX=5 mx.develooper.com. ]

   # Specify a type of 'TXT'
   < you> bot: dns perl.org txt
   < bot> No answers for perl.org

   # Specify a type of 'SOA'
   < you> bot: dns perl.org soa
   < bot> perl.org [ SOA=ns1.us.bitnames.com:dnsoper.bitnames.com:2008011304:5400:5400:604800:300 ]
