The much larger default 64-bit subnet address space of IPv6 should in
principle make traditional network (port) scanning techniques used by
certain network worms or scanning tools less effective.  While
traditional network scanning probes (whether by individuals or
automated via network worms) may become less common, administrators
should be aware that attackers may use other techniques to discover
IPv6 addresses on a target network, and thus they should also be
aware of measures that are available to mitigate them.  This
informational document discusses approaches that administrators could
take when planning their site address allocation and management
strategies as part of a defence-in-depth approach to network
security.  This memo provides information for the Internet community.

This document is a product of the IPv6 Operations Working Group of the IETF.
