Free Secondary DNS
I can’t vouch for the reliability of their service (yet), but secondary.org offers a free Secondary DNS Service. Could be hndy for anyone hosting domains on an ADSL service with only 1 IP address. From their site…
Free secondary DNS is available here. Add redundancy for your DNS by adding an extra DNS server to your list. Great for home users or small sites.
