Yes, I agree that they are PI in disguise. But they are still a way of saying to general end users that there's no such thing as PI space - by general end users, I mean corporations not people like TLD (or ccTLD) operators (they should know full well what's what). Or are we just going to say, if you can create a good enough case then PI exists - come and get it.
PI will come or IPv6 not fly. Face it.
If we (as in RIPE) are going to start handing out longer than /32's then all the RIR's have to make it abundantly clear that they don't support the idea of /32 filters
ARIN and LACNIC already do. RIPE (not NCC) folks are still trying to make policy around people's failure to properly maintain filters. It's like capitulating before the battle even started (looking at actual deployment out there, the few who don't get it [filtering] will learn it the hard way later).
or should they (RIR's) make allocations/assignments (call them what you will) from a global pool for these micro allocations and everyone then shouts about how this specific /32 shouldn't be filtered.
Yes.
ARIN: http://www.arin.net/registration/ipv6/micro_alloc.html (2001:0500::/29) LACNIC: http://lacnic.net/en/registro/index.html "IPv6: 2001:1200::/23 (minimum allocation /48)" "NAPs/IXP in the region: [...] 2001:12f8::/32"
So basically you have to (judging from above statement) expect valid /48 announcements from whole LACNIC space.
And from ARIN space within 2001:500::/29.
How soon do we think the routing tables are going to become unmanageable (and I mean unmanageable by the routers themselves) ?? 3 years, 5 years ??
Can you give some well-funded projection, or just hand-waving FUD?
I can't give any projections - That's why I asked :) I'm sure someone could work out given the current growth rate, how long it would take to cripple todays routers.
Perhaps we ought to be asking the people who design/build the routers what they think their kit will be capable of by then.
They say that they test their RPs for 1 million RIB routes since years. Not the (then) high-end gear you have bought ten years ago, or even only a few years ago where you may have made questionable and/or short-sighted purchase decisions.
We have seen large increases (in % terms) of what routers can now do compared to 5 years ago, what's to say we're not going to see even bigger % increases over the next 5 years.
We don't need. We don't even push (good) 5-year old gear to the limits with today's IPv4 junk DFZ RIB. Give every IPv6 ASN a prefix to announce and we'll add about 10-15% to this RIB. Big deal? I strongly disagree.
We don't push them now ?? - even the big guys ?? If even they don't push their routers hard, then even with phenomenal growth over the next 5 years or so then what ever the current routers are then will probably be able to cope. If the routers can cope then the size of the routing table becomes a non issue - that's what I'm trying to say. Jon
