                       BULK DNS Resource Records
                       draft-woodworth-bulk-rr-09

Abstract

   The BULK DNS resource record type defines a method of pattern-based
   creation of DNS resource records based on numeric substrings of query
   names.  The intent of BULK is to simplify generic assignments in a
   memory-efficient way that can be easily shared between the primary
   and secondary nameservers for a zone.
