Allocation shall be similar in all ways to normal IANA address allocation to RIRs, including but not limited to IN-ADDR.ARPA delegations and WHOIS records. --- Paul Vixie not speaking for ISC not speaking for ARIN -------------------------------------------------------------------- IETF IPv6 working group mailing list ipv6@ietf.org Administrative Requests: https://www1.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
