Abstract

   This document describes a Dynamic Delegation Discovery System (DDDS)

   Database using the Domain Name System (DNS) as a distributed database

   of Rules.  The Keys are domain-names and the Rules are encoded using

   the Naming Authority Pointer (NAPTR) Resource Record (RR).

   Since this document obsoletes RFC 2915, it is the official

   specification for the NAPTR DNS Resource Record.  It is also part of

   a series that is completely specified in "Dynamic Delegation

   Discovery System (DDDS) Part One: The Comprehensive DDDS" (RFC 3401).

   It is very important to note that it is impossible to read and

   understand any document in this series without reading the others.
