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 fewer unique addresses. As a result, it is widely assumed that it would take a tremendous effort to perform address-scanning attacks against IPv6 networks; therefore, 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.
