This module will parse a Zone File and put all the Resource Records (RRs) into an anonymous hash structure. At the moment, the following types of RRs are supported: SOA, NS, MX, A, CNAME, TXT, PTR. It could be useful for maintaining DNS zones, or for transferring DNS zones to other servers. If you want to generate an XML-friendly version of your zone files, it is easy to use XML::Simple with this module once you have parsed the zonefile. DNS::ZoneParse scans the DNS zonefile - removes comments and separates the file into it's constituent records. It then parses each record and stores the records internally. See below for information on the accessor methods.

pear-Net_DNS2 provides (roughly) the same functionality as Net_DNS, but using PHP5 objects, exceptions for error handling, better sockets support. This release is (in most cases) 2x - 10x faster than Net_DNS, as well as includes more RR's (including DNSSEC RR's), and improved sockets and streams support.

Dns2tcp is a tool for relaying TCP connections over DNS.

Net::DNS is a collection of Perl modules to interface with the Domain Name System (DNS) resolver. It allows the programmer to perform queries that are beyond the capabilities of gethostbyname and gethostbyaddr. There are also methods for dealing with creating and parsing dynamic updates packets.

Net::DNS::Async is a fire-and-forget asynchronous DNS helper.

DNS Balance is a load-balancing DNS server which: o Does dynamic load balancing. o Can answer the most proper resolution based on the client's IP address. o Implements "A" record lookups only. This would be good for security. This (FreeBSD) version differs from original in the following: - It works as a daemon - Has ability to write messages to logfile - Can save it's PID

A recursive DNS client for POE

Net::DNS::Codes provides forward and reverse lookup for most common C library DNS codes as well as all the codes for the DNS HEADER field.

The Net::DSN::SEC suite provides the resource records that are needed for DNSSEC (RFC 4033, 4034 and 4035). In addition the DLV RR, a clone of the DS RR is supported (RFC 4431) It also provides support for SIG0. That later is useful for dynamic updates using key-pairs. RSA and DSA crypto routines are supported. For details see Net::DNS::RR::RRSIG, Net::DNS::RR::DNSKEY, Net::DNS::RR::NSEC, Net::DNS::RR:DS, Net::DNS::RR::DLV, and see Net::DNS::RR::SIG and Net::DNS::RR::KEY for the use with SIG0. Net::DNS contains all needed hooks to load the Net::DNS::SEC extensions when they are available. See Net::DNS for general help.

Net::DNS::Resolver::Programmable is a Net::DNS::Resolver descendant class that allows a virtual DNS to be emulated instead of querying the real DNS. A set of static DNS records may be supplied, or arbitrary code may be specified as a means for retrieving DNS records, or even generating them on the fly.
