Edie,

Before we even discuss the use of leases for DNS records we need to
determine if DNS needs a lease for each A or AAAA record.  I maintain as
an initial discussion that this is not necessary.  

Because renumbering is not inherent yet in IPv4 or DHCPv4 I will use my
stateless IPv6 implementation as an example on a "client".

I process IPv6 ND RAs prefix options for valid and preferred liftetimes.
Before an address goes invalid I could delete the DNS AAAA record or
right after.  DNSSEC is not an issue and you need to point out your
concerns in "detail" where it is an issue.  Because if it is I have
input for DNSSEC.  Realize the use of SIG records initially suggested
has completely been re-done so I am not sure which dynDNS security model
your alluding to at this point in the discussion?

Now if the DHCPv6 server wants to delete the clients A record I will put
the same code (reuse) for that on my server.

We need to discuss this in detail but in the present draft per Yakov the
TTL will not work as a strategy.  Nor should the TTL be used in that
manner.  I also have an architecture problem with leases in the DNS
until we talk this through a bit more.
