Undesirable by whom? For a laptop, for example, the most likely cause of a MAC address change is that the user/owner used an administrative command to change it, probably in an attempt at getting privacy. Keeping the same IID would defeat the purpose. On the other hand, if I am managing a big server, I would like to retain the same IPv6 addresses to avoid disrupting service. But then, if I want a fixed address, I would probably ensure that by configuring a fixed address, not by relying on a side effect of automatic address configuration. -- Christian Huitema -------------------------------------------------------------------- IETF IPv6 working group mailing list ipv6@ietf.org Administrative Requests: https://www.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
