My linode is now my personal DNS resolver. I have officially ditched the ISP nameservers from this point forward now that I found unbound. Unbound is a lightweight, recursive resolver that is perfect for your LAN, co-located host, or even a single host. For your single host, emerge unbound, start the service, add 127.0.0.1 to the first nameserver in /etc/resolv.conf. Unbound is setup (by default) to accept connections from localhost and refuse anything else.
