That's completely true; many switch chips cannot route on longer than /64
prefixes, so attempting to do so starts to either heat up the software slow
path, or consume ACL entries, or is simply not supported at all. While
this is arguably a bug, it is also pretty much ubiquitous in the current

Ok maybe I'm overstating it a bit... but there are a lot of those chips out
there, and they are painful.

This looks a typical double standard for me. You are willing to allow
homenet (the network operator in this case is subscribers) to play semantic
in their networks with the bits from 48 to 63, while you disallow ISPs to
set the semantic bits in their networks with the bits from 20 to 48 or 56.

Exactly. I agree we should not block the possibility for the future.
However, I don't agree we should block the current requirements to make the
way for the uncertainties of future. We should first serve the needs today,
then we the better current network will become a better fundamental for our
Hi, Roland,
Thanks for your comments. Yes, the authors will restructure this draft -
making it more an analysis draft rather than a proposal. The pitfalls will
be an very important part for a neutral analysis.
Cheers,

What's the problem if the consumer get /48 as you want, and providers play
their 28 bits (bit 20~47)?
For me, the consumer flexibility looks more uncertain although I don't have

Just to remind people, RIR policy is community driven. If the operations
people feel they need a policy for IPv6 allocations and assignments which
takes accounts of semantic bits, they can derive consensus driven policies
to do it. Its not done in the IETF. There might be an issue with how it
