Just like the last IETF - We'll assign a set of IP Addresses to a set of wires on the table.

On the DNS issue, I would agree with you that their implementation has some serious shortcomings. On the other issue, I think there's something wrong with your customers. I have a computer on my home network running Windows NT 4. It's not a /24 network, it's a /29, and NT4 accepts a .248 netmask without any problem. -- William S.

Randy - The plan is get a couple of hubs and string a handful of thinnet lines to the back of the room for the laptop crowd. People seemed to like this setup at D.C. so we're going to do that again. There is also a computer lab down the hall in the adjacent building with a hundred or so machines.

This can be solved, it's a matter of logistics and procedures, when did you last hear that an airline filled with diesel instead of Jet-A1? -Peter Before anyone statrs to build a very expensive pop, revisit the idea of several locations and geograpghical diversity, as it is close to defend a single locataion, a competing ISP could go around and cut all your wires....

You have 2+2 generators, two in a backroom with it's own proper ventilation shaft, and one in each end of the tunnel that goes across the mountain. (You might concider Jet-turbines). Each generator has it's own fuel supply, and power wiring is redundant. The pop itself should be a -48V DC plant. > > Or the ever present possibility that the building next > > door will have a gas leak and explode? Explosions in the access tunnel is non fatal, and probably some gas- detectors and proper fans would be a good thing to have. > > And what about that house-sized meteor that could come hurtling down? Likely to shake the mountain, so, we build a house inside the cave, and put this house on suspenders (that will provide proper shock absortion). Airconditioning is a separate problem, usally the mountain leeks enough wather (+5 centigrades) that you can run through your heat-exchanger, or you have to drill for wather. If we have several of those locations, all with 24*7 staffin, I think it would be produce a good service, even when there are no customers left. --Peter Ps: Make sure that your external connections are redundant enough, microwave towers ontop are likely to be wiped out.. --::))

They slime things all up, and quickly pull a working solution out of the muck. In fact, I found myself at O'Hare Airport in Chicago early Sunday morning picking up two routers and a bunch of interface cards. Cisco had been working on an unidentifiable prblem, and decided that we may need to unload a couple of our routers so they zipped out a couple of extra routers to us, along with an engineer. Anyway, I know that I can count on their customer support organization to immediately respond to my needs. The ONLY other company I ever worked with that offered (and met) this level of support was HP. Chris

But, for my clients, based on your representation that it is finally working, I suppose that I might be willing to at least allow Sprint in future multi-home bids, as long as the contract specifically requires Sprint to be on better behaviour.
