What about a "IPv6 renumbering considered harmful" or "Unstable DHCP-PD prefix considered harmful" ?

-éric (enjoying my 3-year old /48 or is it 5 years?)

    Mark,
    
    Right. Instant/flash renumbering is not supported in IP networks.
    IPv6 does nothing to help with this, well, assuming a network hiding behind NAT, it makes it harder.
    Apart from "does not work", what more can the IETF say or do here?
    
    Cheers,
    Ole
