The latest and greatest graph can be found at (sorry, no gif or jpeg available currently): ftp://ftp.nic.surfnet.nl/surfnet/net-management/ip/nets.ps Please note the flat-line at the end of the graph: Due to a reconfig of the router I take the samples from during my holidays I am missing some data points :-(. But the last sample points that are in there are well above 40000. __ Erik-Jan.

Now that net99 is assimilated (with the exception of one city), AGIS will begin cleaning up its announcements, as well as implementing access-list 112 inbound. We'll publish the dates and details soon.

From: Avi Freedman <freedman(a)netaxs.com> ... > I'd like to know the answer to this (re: PAIX. No other exchange that I > know of gives IPs for use by non-routers that aren't RA machines). ... But that doesn't stop people from attaching hosts into the NAP infrastructure. I pointed this out on the mae-west list a few weeks ago. There are quite a few providers at mae-west who plug the NetEdge at their end into a FDDI ring which has multiple IP subnets on it, one of them the NAP addresses, and another for their local boxes. Since the NetEdge is a filtering bridge, it seems like it would isolate the traffic, but it DOESN'T STOP BROADCAST TRAFFIC. So you get lots of CDP packets, rwhod packets, RIP packets, internal ARP requests, and who knows what else floating around the entire exchange point. All you need to do is send a single ping to 255.255.255.255 via your NAP interface to see just how widespread this has become. Discussion on the mae-west list basically came down to "no, this shouldn't be how people build their networks" but I don't see any changes: (note that some stuff might be missed because not every ping reply gets back) Stuff in other address spaces: Reply to request 0 from scl-ca-gw3.netcom.net (163.179.51.16), 44 ms Reply to request 0 from scl-ca-gw13.netcom.net (163.179.51.14), 304 ms Reply to request 0 from nntp.mainstreet.net (205.137.63.53), 56 ms Reply to request 0 from sc01-gw1.mainstreet.net (207.5.0.2), 52 ms Reply to request 0 from scl-ca-gw7.netcom.net (163.179.51.7), 48 ms Reply to request 0 from scl-ca-gw2.netcom.net (163.179.51.3), 48 ms Reply to request 0 from scl-ca-gw6.netcom.net (163.179.51.6), 48 ms Reply to request 0 from scl-ca-gw4.netcom.net (163.179.51.4), 48 ms Reply to request 0 from scl-ca-gw12.netcom.net (163.179.51.13), 48 ms Reply to request 0 from sc01-gw2.mainstreet.net (207.5.0.4), 48 ms Reply to request 0 from scl-ca-gw10.netcom.net (163.179.51.10), 48 ms Reply to request 0 from news8.agis.net (205.137.63.52), 48 ms Reply to request 0 from scl-ca-gw9.netcom.net (163.179.51.9), 44 ms Reply to request 0 from scl-ca-gw8.netcom.net (163.179.51.8), 44 ms Reply to request 0 from scl-ca-gw5.netcom.net (163.179.51.5), 44 ms Reply to request 0 from scl-ca-gw1.netcom.net (163.179.51.15), 44 ms Reply to request 0 from news4.agis.net (205.137.63.51), 44 ms Equipment that can't reply properly to broadcasts: Reply to request 0 from 255.255.255.255, 4 ms Reply to request 0 from 255.255.255.255, 1 ms Reply to request 0 from 255.255.255.255, 72 ms Reply to request 0 from 255.255.255.255, 4 ms -matthew kaufman matthew(a)scruz.net

Exactly as many class C's as are not yet being routed, minus those which have been voluntarily returned. I believe the return statistics have been made available to nanog before, so perhaps the keeper of them could do this calculation. -matthew kaufman matthew(a)scruz.net

i think this is somewhat related busy naps and overloaded interconnects and i'm wondering if anyone else has noticed this kind of thing. i've noticed in debugging on my border router at mae west (the only place i actually looked at this) there is a lot of broadcast traffic that shouldn't even be propogated at a nap, such as: Sep 5 09:07:02.424: UDP: rcvd src=205.137.63.52(513), dst=255.255.255.255(513), length=68^M Sep 5 09:07:02.424: UDP: rcvd src=205.137.63.52(513), dst=255.255.255.255(513), length=68^M this is a unix box i'm guessing trying to get information via whod on the fddi ring at mae west. i've logged a large number of these broadcasts this evening, all within milliseconds of each other. seems to me we (collectively) don't want/need to see this type of traffic floating around when we're trying to push real customer traffic through the interconnects. or how about broadcasting bootp/tftp requests across the ring? i've logged an equally large number of these tonight: Sep 5 09:06:12.735: UDP: rcvd src=0.0.0.0(68), dst=255.255.255.255(67 ), length= 308^M Sep 5 09:06:12.735: BOOTP: opcode 1 from host 0.0.0.0 on Fddi10/0, 64508 secs, and even better: Sep 5 09:20:16.714: UDP: rcvd src=163.179.51.7(65044),dst=255.255.255 .255(69), length=29 is someone trying to pull a config (any config) via tftp from whomever happens to have one? this kind of traffic just seems very wasteful and unneeded at the naps. i can't see that this is even useful to the folks doing it. more traffic clogging up the pipes. -brett
