# sudo apt-get install bind9

Instructions on setting it up can be found here

https://help.ubuntu.com/community/BIND9ServerHowto#Caching%20Server%20configuration

In the forwarder section add the opendns server IPs (or any other reliable
DNS servers).

Also a small configuration change needs to be made in
/etc/dchp3/dhclient.conf if you are using dynamic ip addresses (e.g.
wireless roaming network)

Find the line that says
#prepend domain-name-servers

Uncomment it to read

prepend domain-name-servers 127.0.0.1;

Now whenever you reconnect using network manager, your own system will be
used as the DNS server.

BIND will cache DNS responses and will provide faster name lookups. In fact
if you have multiple systems, you can point them to your system for name
lookups (firewall configuration is required though).
