BULK DNS Resource Records
draft-woodworth-bulk-rr-06
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.
