This document describes requirements for how IPv6 address prefixes
should be delegated to an IPv6 subscriber's network (or "site").
With the deployment of IPv6 , several Internet Service Providers
are ready to offer IPv6 access to the public. In conjunction with
widely deployed "always on" media such as ADSL and the expectation
that customers will be assigned a /48 IPv6 unicast address prefix
(see RFC 3513  and section 3 of RFC 3177 ), an efficient
mechanism for delegating address prefixes to the customer's sites is
needed. The delegation mechanism will be intended to automate the
process of informing the customer's networking equipment of the
prefixes to be used at the customer's site.
This document clarifies the requirements for IPv6 address prefix
delegation from the ISP to the site.
