The Net::DNS::ZoneFile::Fast module provides an ability to parse zone files that BIND8 and BIND9 use, fast. Currently it provides a single function, parse(), which returns a reference to an array of traditional Net::DNS::RR objects, so that no new API has to be learned in order to manipulate zone records.

Net::DNSBL::MultiDaemon is the Perl module that implements the multi_dnsbl daemon. multi_dnsbl is a DNS emulator daemon that increases the efficacy of DNSBL look-ups in a mail system. multi_dnsbl may be used as a stand-alone DNSBL or as a plug-in for a standard BIND 9 installation. multi_dnsbl shares a common configuration file format with the Mail::SpamCannibal sc_BLcheck.pl script so that DNSBL's can be maintained in a common configuration file for an entire mail installation. Because DNSBL usefulness is dependent on the nature and source of spam sent to a specific site and because sometimes DNSBL's may provide intermittant service, multi_dnsbl interrogates them sorted in the order of greatest successful hits. DNSBL's that do not respond within the configured timeout period are not interrogated at all after 6 consecutive failures, and thereafter will be retried not more often than once every hour until they come back online. This eliminates the need to place DNSBL's in a particular order in your MTA's config file or periodically monitor the DNSBL statistics and/or update the MTA config file.

Net::DNSBL::Statistics is the Perl module that collects statistics on the interrogation success for a list of IP addresses against a list of DNSBL's. The module is used to implement the reproting script dnsblstat.

Net::Domain::ExpireDate gets WHOIS information of given domain using Net::Whois::Raw and tries to obtain expiration date of domain. Unfortunately there are too many different whois servers which provides whois info in very different formats. Net::Domain::ExpireDate knows more than 40 different formats of expiration date representation provided by different servers (almost all gTLD registrars and some ccTLD registrars are covered). Now obtaining of domain creation date is also supported.

The purpose of this module is to provide user with current list of available top level domain names including new ICANN additions and ccTLDs.

A recursive DNS client for POE

POE::Component::Client::DNS is a wrapper for non-blocking Net::DNS. It lets other tasks to run while something is waiting for a nameserver to respond, and it lets several DNS queries run in parallel.

A Perl POE component that provides non-blocking DNSBL lookups

POE::Component::Resolver performs Socket::GetAddrInfo::getaddrinfo() calls in subprocesses where they're permitted to block as long as necessary.

POE::Filter::DNS::TCP is a POE::Filter for parsing and generating DNS messages received from or transmitted (respectively) over TCP as per RFC 1035.
