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.
DDDS defines a mechanism for using DNS as the database for arbitrary identifier schemes.
Telephone Number Mapping (ENUM) (RFC 6116) is defined as a DDDS application to resolve phone numbers into data stored in the Domain Name System (DNS).
