Again: you are talking about theoretical worst-case absolute numbers. I'm talking about real life.
I guess you would agree with me that it's currently no problem at all to obtain an ASN and IPv4 PI if you want to multihome. Right? This has lead to about 17k active ASN out there. Which translates to 17k-20k (let's give some headroom for special routes for anycast etc) IPv6 PA/PI routes. Where is your problem? I don't see multiple million of end sites doing BGP multihoming. Not now, not in ten years. It's not that we have hundred of thousand of NEW people JUST WAITING for the availability of PI out there.
So, when do you estimate will we see let's say more than 100k active ASNs out there? And even then we're talking about 100k, not 1 million, not 10 million.
once again: FullACK. ...but i certainly get tired having that specific discussion with always the same specific arguments every few months, so no much motivation for writing anything more than "FullACK" ATM. But probably it's better than saying nothing at all on that topic (like most people who might not even care). [...]
There is no REAL multihoming without PI yet. And the IETF recently narrowed down the road they want to take (solution space) that guarrantees that the result won't fit people's needs. The multi6=>shim6 transition was (for me and quite a few others) the "end of all hope".
Why?
Because the outcome won't provide what people do ask for.
And what are people asking for?
At least the same set of features as IPv4 PI BGP multihoming with no new added significant downsides.
Perhaps folks should start listening to that instead of sticking the head into the sand.
Time will tell, there either will be PI Space (like in the IPv4 world), or IPv6 won't get any relevance in "the Internet" within the next 20years (IMNSHO). If some folks want to stick their heads in the sand - let them. -- ======================================================================== = Sascha Lenz SLZ-RIPE slz@baycix.de = = Network Operations = = BayCIX GmbH, Landshut * PGP public Key on demand * = ========================================================================
