CurveDNS is a forwarding nameserver adding DNSCurve to DNS,
and it's the first publicly released forwarding implementation
that implements the DNSCurve protocol.
dnsdbck verifies consistency of DNS information in an SQL database.
It is part of dnstools, a set of utilities for DNS management and related
tasks.
AnyEvent::CacheDNS provides a very simple DNS resolver that caches its results
and can improve the connection times to remote hosts.
Net::DNS::Match is a Perl extension for testing domains against another
list of domains (similar to Net::Patricia but for FQDNs).
This is Net::Bonjour, a set of perl modules to utilize DNS for service
discovery. This method of service discovery is branded as Bonjour by
Apple Computer.
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.
POE::Filter::DNS::TCP is a POE::Filter for parsing and generating DNS
messages received from or transmitted (respectively) over TCP as per RFC
