about routing bits, I missed your point about people being able to ping an IX interface... I'd submit that in many networks the path to the nexthop may be a vastly different one than the path to 'the broken thing' through the isp/ixp/isp set of routers. I meant: Is the nexthop in your (the ixp

, but can't find a reference really quick that they get transit for it from a couple of providers so those that don't peer still have the route. I mean really, you have a block. If your IXP matters it's already taking up space in all of the largest ISP's tables anyway, so there's no saving a route

routers may use several IP prefixes for routing, how often does the IP prefixes have their own AS? 2. For type 2, all peers connected to the IXP must work in the same subnet required by Ethernet rules. Is possible that the subnet IP prefixes belong to some private IP address space, such as 192.168.x.x
