Abstract

IPv6 offers a much larger address space than that of its IPv4 counterpart. The standard /64 IPv6 subnets 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 classic IPv6 address scanning attacks have been considered unfeasible. This document updates RFC 5157 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.
