I ran into the problem that when registering my domain. I was required to list two different public IPs as nameservers. I got a friend to host my secondary, thus solving the problem. Theoretically, if you were to set a random DNS server (say, your ISPs) as your secondary with the root servers without actually setting it up as a secondary, what percentage of the lookups would fail? My understanding is that DNS will always try the primary first, and in my case, with a single static IP, if my DNS fails, chances are so will everything else. Seems like it wouldn't much matter to me. --- Nick Rogness <nick@rogness.net> wrote: > On Thu, 21 Jun 2001, Rick Hamell wrote: > > > > > What is the best way to setup secondary DNS?
