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 () scruz net - - - - - - - - - - - - - - - - -
