This document specifies extensions to IPv6 Neighbor Discovery to carry site prefixes. The site prefixes are used to reduce the effect of site renumbering by ensuring that the communication inside a site uses site-local addresses. This protocol requires that all IPv6 implementations, even those that do not implement this protocol, ignore all site-local addresses that they retrieve from the DNS when the AAAA or A6 RRset contain both global and site-local addresses. If the RRset contains only site- local addresses those addresses can be used.
