Abstract

This document states clearly that when a DNS resolver receives a response with a response code of NXDOMAIN, it means that the domain name which is thus denied AND ALL THE NAMES UNDER IT do not exist. This document clarifies RFC 1034 and modifies a portion of RFC 2308: it updates both of them.
