PowerDNS Recursor 3.1.6 (Default branch)
With a small codebase, the PowerDNS Recursor is an advanced resolver currently serving the DNS resolving needs of over 40 million Internet connections. Besides high performance (using kqueue or epoll, over 50 thousand qps on commodity hardware), it provides advanced anti-spoofing measures. In addition, the program caches server performance and timeouts, making it both network and user friendly. It also has built-in hooks for making graphs with rrdtool, providing insight into nameserver performance.License: GNU General Public License (GPL)Changes:
This version fixes two unfortunate bugs, one with slight security implications. The first bug impacts heavily loaded servers trying to resolve domains with nameservers broken in a specific way. The other bug implies that the new random generator was not used for UDP source port selection.Image

       notify <domain>

       ping   Check if the server is alive.

       purge [<record>]
	      Purge entries from the packet cache. If the record name ends with a dollar ($) all entries that end with that name are  removed.	If
	      no record is specified the entire cache is purged.

       rediscover
	      Instructs backends that new domains may have appeared in the database, or, in the case of the Bind backend, in named.conf.

       retrieve <domain>
	      Retrieve a slave domain from its master. Done nearly immediatly.

       set <variable> <value>
