Sorry about somewhat OT content, but... For some intended uses, NDproxy is awfully complex way of achieving a result, which would much easier to do as follows:
1) ISP give /64 2) use internally longer prefix (68 or 72), reserve the one (based on ID assigned to the ISP link) for the ISP link, and use rest for own private purpose. 3) Run modified router, that taks in /64, and addversises the longer prefix on other links with different different prefixes. This would work just fine, if nodes on internal network take the RA prefix length as is, and just trunctate their ID-parts from higher ends (or they could just generate ID randomly). Throw away all this sillyness with fixed 64-bit ID etc.. -------------------------------------------------------------------- IETF IPv6 working group mailing list ipv6@ietf.org Administrative Requests: https://www1.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
