As long as this stuff generally works, nobody's likely to replace it. ---------------------------------------------------------------------- I have seen a LOT of that equipment out there in places like universities and whatnot. scott.

Eventually this stuff falls out of the internet or gets consigned to roles where it can't do much in the way of damage. The timescale over which this happens is extremely long. ipv4 exhasution has it's own timeline and I daresay most network operators will be focused on: Deployment of new resources (ie deployment of ipv6) Not causing damage to or requiring modification of the installed base. It seems clear to some if not to everyone that use of 240/4 requires the modification of the installed base. IPV6 deployment is not going to affect the installed base with the exception of the devices that already support it. the ipv4 internet will continue to operate as it does today except perhaps with additional pressure on address space constraints, growth of large nated space and erosion of end-to-end reachability.
