The current Internet climate poses serious threats to the Domain Name
System.  In the interim period before the DNS protocol can be secured
more fully, measures can already be taken to harden the DNS to make
'spoofing' a recursing nameserver many orders of magnitude harder.

Even a cryptographically secured DNS benefits from having the ability
to discard bogus responses quickly, as this potentially saves large
amounts of computation.

By describing certain behavior that has previously not been
standardized, this document sets out how to make the DNS more
resilient against accepting incorrect responses.  This document
updates RFC 2181.  [STANDARDS TRACK]
