Speed up Internet access by using Persistent DNS caching with Pdns - Ubuntu Linux

pdnsd is a proxy DNS server with permanent caching (the cache contents are written to hard disk on exit) that is designed to cope with unreachable or down DNS servers (for example in dial-in networking).

pdns installation:
Open up the terminal Application > Accessories > Terminal and type following command:

sudo apt-get install pdnsd
