However, my impression is that we >are seeing increasing ISP concentration (except, maybe, close to >the edges of the network, where it makes little difference) and >less of that traditional type of multihoming. There's tons of multihoming. Every medium sized or larger business wants multiple upstreams for reliability. They typically get a chunk of PA IPv4 addresses from each upstream. This is a big reason why providers don't implement BCP38. A customer has one block of addresses from provider A and another from provider B. In general each provider only knows about its own address block, but the traffic comes from both blocks, and the customers get rather annoyed if a provider doesn't accept their traffic. ("If you don't want our $20K/month, we're sure we can find someone else who does.") Trying to keep track of what customer has what block of someone else's address space is hopeless, so they just turn off the filters for the multihomed customers. This is of course a place where v6 wins, since the customer can get their own block of PI space, but then there's all those other v6 deployment problems. R's, John
