Maintenance Blog

Net::DNS version 0.61 corrects an error that was introduced in 0.60 and was reported by the maintainers of OTRS and various other folk.

In several places in the code we tried to modify $_, the resulting error was: Modification of a read-only value attempted 

See Changes for details.

Version 0.60 is a maintenance release.

The release contains a number of bug fixes and a few new features.  Highlights:

• IPSECKEY RR support
• Improvements to check_soa code, mainly in the way it deals with negative caching
• The dependency of Net::IP in the actual code was dropped. It is still needed for the tests. (Erratum (16 July 2007): Dependency dropped for Net::DNS::Resolver only, the dependency still exists for Net::DNS::Nameserver and a few tests)
• Cleanup of Question.pm
  • This involved a minor change to the API for reverse IP lookup.  Changing qtype to PTR is now performed for A and AAAA only.  This allows queries for NS and SOA records at interior nodes to be specified using the address prefix.  Type ANY queries now also produce the expected result.
  • Support for RFC4291 IPv6 address and IPv4 prefix notation
• At some points where the code used to 'die' it now spits out a warning.
  • Labels longer than 63 octets do not cause your code to die, but are truncated.
  • Instead of dying the SSHFP returns undef when the fingerprint algorithm is unknown.

Dick Franks has contributed a lot of the fixes and features.

This weekend, 10 years ago, Michal Fuhr announced Net::DNS on the comp.lang.perl.modules newgroup:.

I've been working on a general interface to the DNS resolver, allowing the programmer to look up any record type instead of just A (gethostbyname) and PTR (gethostbyaddr). I hope to have it finished by the end of Jan 1997; in the meantime, there's some info about it at:

http://www.dimensional.com/~mfuhr/perldns/

Although the module isn't available yet, there are a few manpages that show what you'll be able to do. The Net::DNS and Net::DNS::Resolver manpages have some code fragments as examples.

I originally called the module DNS but my current choice is Net::DNS, which seems more consistent with the modules for other protocols such as Net::FTP, Net::SMTP, etc. I'm open to other suggestions.

I'd appreciate any feedback on the info I've provided so far. Thanks.

Version 0.59 is a maintenance release.

A number of patches that revolved around the resolution of IPv6 domains have been applied. Dick Franks is acknowledged for his elegant, albeit dense, contributions.

The Question new() method and the Resolver search() have been modified slightly. Please consult the Changes for details.

Please report problems through rt.cpan.org

Version 0.58 is a bug fix maintenance release.

Among the bug fixes documented in Changes are fixes for handling of persistent sockets for Net::DNS::Resolver, fixes for IPv6 tests, fixes in the support for SPF, RFC comform (non)compression behavior of domain names in SRV and NAPTR RRs.

The people reporting the bugs and/or providing patches are acknowledged in the Changes file.

In a recent e-mail thread about misbehaving recursive nameserver David Ulevitch wrote:

Lesson: perl -MNet::DNS::Nameserver -e ‘return new(“$qname $ttl $qclass $qtype $rdata”)’;

…does not a recursive nameserver make…

Version 0.57 contains a minor fix to the test scripts.

In version 0.56 a counter, which determines the number of tests to be skipped when IPv6 is not available, was not increased. That made the test fail whenever v6 is not installed.

Net::DNS Release 0.56 and Net::DNS::SEC Release 0.14 are now available from CPAN.

In Net::DNS::SEC a bug got fixed in the key-tag checking code which gave problems with RSAMD5.

In Net::DNS we introduced

• Implemented SPF (typecode 99)
• Implemented an rrsort() function using this function you can sort various RRsets on their properties see Net::DNS documentation for details
• Removed duplicated TCP code and fixed a possible collission in use persistent sockets for AXFR and queries.
• Fixed fallback from IPv6 to IPv4 transport in the Nameserver
