Software Update: PowerDNS 3.5.3

PowerDNS is a dns server with a database as back-end, which makes it easy to manage a large number of dns entries. In late April 2006, the developers decided to release the two parts that make up PowerDNS, a recursor and an authoritative name server. This allows a new version to be released faster, according to the developers. The developers have released PowerDNS Recursor 3.5.3. The announcement of this release looks like this:

Hi everybody,

version 3.5.3 of the PowerDNS Recursor is now available from https://www.powerdns.com/downloads.html

Kees Monshouwer provides native RHEL5/6 packages at http://www.monshouwer.eu/download/3rd_party/pdns-recursor/

Full release notes, with clickable links, are available from:

3.5.3 is the best version of the PowerDNS Recursor currently available, and we recommend upgrading to it.

Here is a text only version:

This is a bug fix and performance update to 3.5.2. It brings serious performance improvements for dual stack users.

Changes since 3.5.2:

• 3.5 replaced our ANY query with A+AAAA for users with IPv6 enabled. Extensive measurements by Darren Gamble showed that this change had a non-trivial performance impact. We now do the ANY query like before, but fall back to the individual A+AAAA queries when necessary. Change in commit 1147a8b.
• The IPv6 address for d.root-servers.net was added in commit 66cf384, thanks Ralf van der Enden.
• We now drop packets with a non-zero opcode (ie special packets like DNS UPDATE) earlier on. If the experimental pdns-distributes-queries flag is enabled, this fix avoids a crash. Normal setups were never susceptible to this crash. Code in commit 35bc40d, close ticket 945.
• TXT handling was somewhat improved in commit 4b57460, closing ticket 795.
