Since this is the BIND users list, I assume you mean name servers.

Yes, this is built into the DNS. You should always have authoritative name
servers at different locations, so that they're not all taken out by e.g.
a single network outage. As long as all of these servers are listed in the
parent zone (e.g. "net."), name resolution will work as long as one of
them can be contacted.


Unsecured email can be monitored, falsified, altered
and repudiated. Please use PGP. Help is available
at <URL:>. My
public keys can be downloaded from key servers.
