A week or more ago someone posted in NANOG or elsewhere a site that had made a comparison of the IPv6 BGP table sizes of different operators (i.e. HE, Cogent, Sprint, etc), making the point that a full view might take multiple feeds. I think that website also had text files with the comparisons. But I can't find that e-mail or website anywhere! Does anyone know where that listserv posting or website is? Frank

Not sure what route-server you are speaking of, but a quick peek at what we send on a customer session I see: NTT (2914) sends 3868 prefixes. If the route server contacts me in private, we can likely set up a view from 2914 or 2914-customer perspective. - Jared On Dec 21, 2010, at 5:18 PM, Frank Bulk wrote:

The provider who gave me the information didn't tell me what public route server they used. They didn't analyze all ASNs, just the handful I listed. It would be interesting if someone set up a daily report that documented all the IPv6 routes an ASN carried, and then tracked both the absolute numbers and percentages over time.

I could not find this information on any Wikis, but this is the sort of thing that would be nice to be able to find out without posting on the list or asking around (obviously.) I have quickly made a couple of entries with simple enough formatting that anyone can go onto Wikipedia, click Edit, and add what they know.

'Maximum Prefix Length' may be an over-simplifying metric. FWIW, we're certainly not a major transit provider, but we do allow /48 in the designated PI ranges but not in the PA ranges. So the question is not necessarily just about the prefix length used because it might vary by the prefix. -- Pekka Savola "You each name yourselves king, yet the Netcore Oy kingdom bleeds." Systems.

I know it is an over-simplification. If someone wishes to edit the page to provide more specific details about the route filtering policy for a given transit network, Wikipedia is pretty easy to edit.

Hi, I love that people compare absolute numbers but have you also checked how much noise is in there? Back in the times when I was handling a /32 for someone, I created really strict filters and was shocked. The last version (really outdated these days, so don't use it, Cisco style) was here: http://sources.zabbadoz.net/ipv6/v6-prefix-filter-20080703-public.cfg People might say that it would not be helpful at all as we want IPv6 deployed but on the other hand people apply their doings of the last 10 years 1:1 to IPv6 and continue on the same mistakes which will not be helpful either.

Indeed...
I would really love to see weekly Routing Reports for IPv6 as we have them for legacy IP rather sooner than later.
This would provide statistics and might be useful from historical POV, but I fear the operational impact of published IPv4 Routing Table reports is close to zero. (E.g.

Actually, at the last NANOG meeting there was some value in calling out one ISP. They didn't respond publicly but several folks came over and said they were going to take corrective action. - Jared

I had a quick look at the diff between routes given to me by AS174 and 6453 and other v6 peers and here is what I found based on missing /32s. (I excluded /48s for now) There are some 490 /32s missing from Cogent from my network in Toronto, Canada. The majority are paths via just 6939. Of those that are not just 6939, I see them via the following AS paths. 11647 6453 293 11647 6453 701 668 11647 6453 30071 13645 11647 13030 15716 11647 6453 5511 11647 6453 6830 11647 6453 25137 11647 6453 30071 2549 11647 6453 30071 10318 11647 6453 6762 7303 11647 6453 30071 11647 6453 6762 8280 11647 6453 13030 11647 13030 11647 6453 701 11647 6453 6762 11647 6453 5511 8346 11647 6453 30071 11647 6453 13030 8271 11647 13030 8271 11647 6453 13030 33845 11647 6453 701 18061 9555 11647 6453 6762 7642 11647 6453 30071 6536 11647 6453 701 18750 11647 6453 30071 19151 11647 6453 701 26773 11647 6453 30071 10326 11647 6453 30071 19151 16842 11647 6453 30071 19151 31877 11647 6453 30071 19151 22911 11647 6453 30071 13911 11647 6453 30071 7786 11647 6453 30071 13911 14595 11647 6453 6762 7303 4270 11647 6453 6762 7303 4270 27770 11647 6453 6762 7303 4270 5692 11647 6453 13030 48218 11647 13030 48218 11647 6453 13030 20634 11647 13030 20634 11647 6453 701 12702 24807 11647 6453 6830 11647 6453 5511 8697 11647 6453 6762 31463 11647 13030 9191 11647 6453 13030 25164 11647 13030 25164 11647 6453 13030 16242 11647 13030 16242 11647 6453 13030 28717 11647 6453 13030 25563 11647 13030 25563 11647 6453 5511 3215 11647 6453 5511 3215 11647 6453 5511 3215 11647 6453 5511 12493 11647 6453 13030 44573 11647 6453 13030 35366 11647 6453 13030 29430 11647 13030 29430 11647 6453 13030 21232 11647 13030 21232 11647 6453 13030 47617 11647 13030 47617 11647 6453 6830 20825 11647 6453 6762 8953 11647 6453 13030 15216 11647 13030 15216 11647 6453 13030 11647 13030 e.g. 2607:f078::/32 11647 6453 701 18750 11647 6939 18750 and 2a01:c910::/32 11647 6453 5511 3215 11647 6939 5511 3215
