From: Phil Howard <phil@whistler.intur.net> :> That's fine. As long as they don't mind spending time and money renumbering :> their entire network once it gets connected to the internet. : :That's my point. With real addresses, it addressed the issues of having to :renumber when new business interconnections were made, or when any of them :decided to get on the Internet. NAT was not viable then, as it is today. To clarify, I was not arguing against using real addresses. What I was had a problem with was your statement that suggests that this network of companies in any way resembles the internet. It doesn't. Companies only need to be worried about the subnets that they can "see". If they are connecting to two separate companies that are using the same address space, this will obviously create a problem. However, it only takes some common sense to resolve such problems. There is an awful lot of RFC1918 space available. --Adam
