In fact, majority of network hosts are not "Publicly Routeable" for the simple reason that they're sitting behind firewalls, or have dynamic addresses. > without any translation > bottlenecks (and yes, there *are* translation bottlnecks on a setup > with several thousands IPs running through a single NAT box), Are you trying to do NAT at OC-3? :) Actually, a newer faster PCs can, probably, do that at even higher bitrates :) It is _very_ easy to install as many NATs in parallel as you wish, simply by segmenting private address space, and routing different segments through different NAT boxes.

No, I agree that having these things available in the initial design is nice; but that alone does not justify redoing the entire network from scratch, since pretty much the same effect can demonstrably be achieved using the already-deployed technology. --vadim |
