Ipv6 Address Allocation Guideline • RFC 3177 recommends the following : A single PC, with no additional need to subnet, dialing-up from a hotel room may receive its /128 IPv6 address for a PPP style connection as part of a /64 prefix. • Give Home/SOHO a permanent /64 – single link • Short-lived /64 from a prefix-pool A Separate /64 is assigned each user/interface. The prefix is advertised in RA’s and a route is installed in the RIB.
