IPv6 Address Assignment to End Sites

RFC 3177 argued that in IPv6, end sites should be assigned /48 blocks
in most cases. The Regional Internet Registries (RIRs) adopted that
recommendation in 2002, but began reconsidering the policy in 2005.
This document revisits and updates the RFC 3177 recommendations on the
assignment of IPv6 address space to end sites. The exact choice of how
much address space to assign end sites is an issue for the operational
community. The role of the IETF is limited to providing guidance on
IPv6 architectural and operational considerations. This document
reviews the architectural and operational considerations of end site
assignments as well as the motivations behind the original 3177
recommendations. Moreover, the document clarifies that a one- size-
fits-all recommendation of /48 is not nuanced enough for the broad
range of end sites and is no longer recommended as a single default.
This document updates and replaces RFC 3177.
