In january I will send out a note to all the folks still announcing 6bone prefixes to remind them that they should be shutting it down per 6/6/6. There doesn't seem to be a large movement in doing so yet...
C. Discussion on: Global IPv6 routing table status (Gert Doering)
Maybe something related might be noted here, in the global routing tables I've seen for instance, just a 'random' targetted pick. http://www.sixxs.net/tools/grh/lg/?find=2001:2000::/20 [Notez bien: the question here is about what is going to become the common policy and what is going to happen to the ipv6 routing, it is not to 'attack' or critize an ISP on what they are doing] 2001:2000::/20 announced by AS1299 (TELIANET) 2001:2040::/32 AS3301 (TELIA-SWEDEN) 2001:2060::/32 AS1759 (SONERA-TRANSIT-AS) No route6 for these 3 prefixes and no inet6nums exist for the the two /32's. Which leads me to a couple of questions: - is it mandatory to register route6's and inet6num's or is it just 'being nice' - is the trend going to be that >/32's will be announced as separate /32's? This of course means that the ISP can be found under one block but still affects the number of routes in the routing table. One could filter the smaller ones if the parent route is present. The idea of minimizing routing table size (yes that is not an issue now, but behold the future) is totally gone when ISP's will do this. I do understand why: to make the branches independant and attract the traffic as local as possible. On the otherside there are also ISP's simply requesting multiple separate /32's from the various RIR's. eg UUNet: 2001:0600::/32 - Europe 2001:4440::/32 - Hongkong 2001:4441::/32 - Australia 2001:4442::/32 - Japan 2001:0588::/32 - South Africa (I am ignoring the 6bone block they still have, with 1 other already returned, as that one will disappear anyway) The question in case of this setup is, why didn't they get 1 block? The generic question: what is the correct plan for these setups?
D. Report(s) about *actual* v6 traffic volume as compared to v4? *what's real* out there, not what's on powerpoint? (input from the audience)
http://www.sixxs.net/misc/traffic/ :) Not much, but it is a bit and for the moment declining a bit weirdly enough. <SNIP>
For example, address fragmentation, a key problem in IPv4, degrades address lookup performance in routers. Thus, a well-designed address allocation policy needs to minimise fragmentation while using the address space efficiently.
