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.
