<abstract>
<t>
   The Domain Name System requires that multiple servers exist for every
   delegated domain (zone).  This document discusses the selection of
   secondary servers for DNS zones.  Both the physical and topological
   location of each server are material considerations when selecting
   secondary servers.  The number of servers appropriate for a zone is
   also discussed, and some general secondary server maintenance issues
   considered.
