David you know as well as I do that DNSSEC is a orthognal
issue here.
My understanding, which may well be wrong, is that:
- stateless auto-configuration assumes the client will update the
address to name association once it has obtained the address.
- In order to do this, the DNS server needs to support Dynamic DNS.
- If DNSSEC is in use, it requires the use of on-line signing keys.
- Security folks get unhappy when you mention on-line signing keys.
Solution?
- Don't have address to name associations
- Don't worry about (or accept lesser) security on address to name
associations.
Of course the DNSSEC bit is sort of moot, as I suspect there aren't a
whole lot of ISPs in a position to support dynamic updates from
clients...
