 The IESG has approved the Internet-Draft "Selection and Operation of
  Secondary DNS Servers" <draft-ietf-dnsind-2ndry-06.txt> for
  publication as a Best Current Practices RFC. This document is the
  product of the DNS IXFR, Notification, and Dynamic Update Working
  Group. The IESG contact persons are Jeffrey Burgan and Thomas Narten.

Technical Summary

  The Domain Name System (DNS) requires that multiple servers exist for
  every delegated domain (zone). A number of problems in DNS operations
  today are attributable to poor choices of secondary servers for DNS
  zones. The geographic placement as well as the diversity of network
  connectivity exhibited by the set of DNS servers for a zone can
  increase the reliability of that zone as well as improve overall
  network performance and access characteristics.

  This document discusses many of the issues that should be considered
  when selecting secondary servers for a zone. It offers guidance in how
  to best choose servers to serve a given zone. 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 are considered.

Working Group Summary

   The Working Group last call produced no significant issues with this
   document.

Protocol Quality

  This document has been reviewed by Jeffrey Burgan and Thomas Narten
  of the IESG.
