Title : Network Reconnaissance in IPv6 Networks

Abstract:
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 formally obsoletes 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.
