The IETF is recommending that the DNS mechanisms to
support IPv6 stay essentially the same as those already
in use with IPv4 today. To our opinion, in the realm of
multi-homed networks, the techniques used in IPv4 can't
all be applied since they have scaling problems.
Specifically, if the same prefix is advertised by multiple
ISPs, the routing tables will grow as a function of the
number of multihomed sites.
I fail to see the relation between DNS and the number of
prefixes being advertised.
As far as scalability is concerned, it is clear that the
mechanism currently being used with IPv4 is not very
scalable, but is reserved to multihomed ISPs/LIRs at this
time and it is generally admitted that one prefix per LIR
would remain a reasonably manageable number even in the
long run. End-sites will likely require a multihoming
solution that is aggregatable.
