RE: v6 & DSL / Cable modems [was: Private use of non-RFC1918 IP space (IPv6-MW)]

So it fails in scenarios where enforcing network policy is important.

If the policy is address specific, perhaps. If the policy is segment specific, no prob. /TJ PS - for emphasis, I am not arguing strictly for or against either SLAAC or DHCPv6. Both can work, and IMHO should be allowed to do so where desirable.
