Dynamic Delegation Discovery System

Dynamic Delegation Discovery System

Defined in RFC 3401, RFC 3402, RFC 3403, RFC 3404, and RFC 3405.

From RFC 3401:

The Dynamic Delegation Discovery System is used to implement lazy binding of strings to data, in order to support dynamically configured delegation systems. The DDDS functions by mapping some unique string to data stored within a DDDS Database by iteratively applying string transformation rules until a terminal condition is reached. This document defines the entire DDDS by listing the documents that make up the complete specification at this time.

DDDS defines a mechanism for using DNS as the database for arbitrary identifier schemes.

Enum (RFC 6116) is defined as a DDDS application to resolve phone numbers into data stored in DNS.
