# 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).
