making the host ("interface ID" in IPv6-speack) to be fixed length, with bigger bitwidth, makes IPv6 address independent from the hardware interface layer. today, i see the following horror story a lot: - use like /28 or something for an IPv4 subnet - there are 15th computer installed, no room for the new computer - renember and get /27 - repeat it with (prefix length + 1) - repeat it with (prefix length + 2) - ... today the most expensive cost is the human labor cost. one less IT guy = happier management level. itojun -------------------------------------------------------------------- IETF IPv6 working group mailing list ipv6@ietf.org Administrative Requests: https://www1.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
