Technical Summary This document explains a current convention for identifying a particular name server out of a set of servers in an anycast cloud or behind a load balancer. It explains key disadvantages of this practice and discusses a set of requirements for an improved mechanism. Working Group Summary This document evolved from a purely documenting informational draft into a requirements document after the WG determined that a single dedicated DNS based information query had operational disadvantages. There was some discussion about splitting the documentation part and the requirements part, but the WG decided to keep it as is. Protocol Quality David Kessens reviewed this document for the IESG. The DNS RR based convention as documented in this draft has been supported by multiple vendors of DNS server software.
