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    192.168.2.6    68.105.28.12    DNS    87    Standard query PTR 174.224.125.74.in-addr.arpa
8    0.262071    192.168.2.6    68.105.28.12    DNS    86    Standard query PTR 39.227.125.74.in-addr.arpa
31    0.840231    68.105.28.12    192.168.2.6    DNS    272    Standard query response PTR lax02s01-in-f14.1e100.net
29    0.825752    68.105.28.12    192.168.2.6    DNS    270    Standard query response PTR dfw06s06-in-f7.1e100.net

 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.

Yay.
