Tons of DNS requests from pidgin - googletalk

So I was getting TONS of DNS requests from my computer.  I had to figure out what was going on here's 2 requests and responses I've arbitrarily yoinked out of a wireshark dump:
2    0.000436    DNS    87    Standard query PTR
8    0.262071    DNS    86    Standard query PTR
31    0.840231    DNS    272    Standard query response PTR
29    0.825752    DNS    270    Standard query response PTR
 My friend suggested nscd (name service cache daemon) which was installed, but not active... I looked around for more information on it and it seemed to be more for authentication caching than DNS caching.

I googled for DNS caching on arch and I found pdnsd

Set it up according to the wiki, with a few tweaks, systemctl enable and reboots later... the DNS flood is over.
