Technically speaking, you don't need two domain servers.  Any good implementation would have a backup (secondary) name server listed, though.  This would prevent problems in resolving domain names to IP addresses if your server ever went down.  When you register a domain, you tell the entire world what server is authoritative for your domain.  This means that another DNS may have information about what IP your domain is on, but your server is the final authority.  If you have a secondary DNS set, then that will be authoritative also.

Example:  At my company, we have one domain server in our server room.  I then had RMI, our service provider, set their DNS to update from my DNS server.  Whe then changed the registration for our domain to list RMI's server as primary and our server as secondary.  This means that if I need to change a DNS entry I do it on my server here.  RMI will update their DNS during the next scheduled update and then the change will propogate through the internet.  It also means that RMI's DNS ends up getting most of the traffic since it's primary.  It also has less of a chance of failure since they monitor it 24/7 (in theory)

Bottom line:  You don't need two servers at your location, but having someone else's DNS syncing with yours to use as a secondary would be a good idea.  Maybe there is someone else with their own domain that would like to use your server as secondary.

  Hello all,
   
  Is it necessary to have two servers running to host your own domains?  I have been playing around with virtualhosts in Apache and nameserving, but do not know exactly whats needed to host my own domain.

  I have 1 static IP which never changes, but beyond that - thats all.  If I register for a domain I am prompted to enter 2 nameserver addresses...  ns1 and ns2...    ??

  Any help appreciated.
