the current BCP from the RFCs disagrees with you.
No, I just disagree with it
Is it wasteful? Yes. However, the practice is Internet-wide. Allocations no longer in use can be returned to the registries.
APNIC used to hand out /35s but you can upgrade to a /32 for free!
As for HE, I don't really see the purpose in allocating TWO /64's just to have one that has an X::1 and X::2 that simply ping each other to make certain the tunnel still works (effectively a /126).
Erm don't you mean 1 /64 for the PtP ? At least that's the only allocation I'm aware of and currently abusing
You really only need a /128 for the PtP connection, I also thought you needed network/broadcast yesterday then I remembered they did away with them in IPv6.
of 2001:470::/32 should be routed over the tunnel anyway (if not ::/0, 2000::/3, or other subnet greater than /32
It's been a while since I played with IPv6 serious (2002 or there abouts), back then we were only supposed route 2000::/3 not ::/0 has something changed or are people just being lazy and routing everything when they shouldn't be?
I vaguely recall the ::/0 shouldn't be routed because it contained multicast space as well as unicast.
Remember that even with any tunnel, one can additionally use the 6to4 mechanism - and should have the 2002::/16 route sent to the primary IPv6-encapsulation interface. With Linux, I've seen the source code that will auto-extract the IPv4 component of such addresses and auto-tunnel the packets to the appropriate host. I don't know if KAME-based IPv6 stacks have that encoded or not (e.g. freeBSD). Sending 6to4 over a different IPv6 tunnel from a dual-stacked host is "taking the long way around." However, as 6to4 along with the IPv6 tunnel service here and elsewhere are transition mechanisms, in a purely native IPv6 Internet, they will eventually disappear.
Ok now you've got me, I'm using linux but I'm not entirely sure what you're talking about here.
As far as DHCPv6 is concerned, part of the original plan for IPv6 is that such would be unnecessary. IPv6 is meant to be "big brother's dream" - everything wired to everything else all the time.
Yes and I have a nice pair of 240v wires here big brother can stick up his you know what
