Abstract
This document discusses the use of the Domain Name System (DNS) for
storage of E.164 numbers. More specifically, how DNS can be used for
identifying available services connected to one E.164 number. It
specifically obsoletes RFC 2916 to bring it in line with the Dynamic
Delegation Discovery System (DDDS) Application specification found in
the document series specified in RFC 3401. It is very important to
note that it is impossible to read and understand this document
without reading the documents discussed in RFC 3401.
