A new version of I-D, draft-ietf-opsec-ipv6-host-scanning-06.txt
has been successfully submitted by Fernando Gont and posted to the
IETF repository.

Name:		draft-ietf-opsec-ipv6-host-scanning
Revision:	06
Title:		Network Reconnaissance in IPv6 Networks
Document date:	2015-02-05
Group:		opsec
Pages:		33

   IPv6 offers a much larger address space than that of its IPv4
   counterpart.  An IPv6 subnet of size /64 can (in theory) accommodate
   approximately 1.844 * 10^19 hosts, thus resulting in a much lower
   host density (#hosts/#addresses) than is typical in IPv4 networks,
   where a site typically has 65,000 or less unique addresses.  As a
   result, it is widely assumed that it would take a tremendous effort
   to perform address scanning attacks against IPv6 networks, and
   therefore brute-force IPv6 address scanning attacks have been
   considered unfeasible.  This document updates RFC 5157, which first
   discussed this assumption, by providing further analysis on how
   traditional address scanning techniques apply to IPv6 networks, and
   exploring some additional techniques that can be employed for IPv6
   network reconnaissance.  In doing so, this document formally
   obsoletes RFC 5157.

Please note that it may take a couple of minutes from the time of submission
until the htmlized version and diff are available at tools.ietf.org.
