- Private X.25 networks don't have assigned network numbers. The number
- you're thinking of is an X.121 address. X.121 addresses begin with a
- DNIC, Data Network Identification Code. DNICs for the United States
- are passed out by either Dep't of State or the FCC, I can't remember
- which. These folks are working from allocations made by the CCITT.
- However, you can't have one, because those are only for public
- networks. Really, you don't need one, anyway. It's only useful if you
- connect to a public X.25 network.
-
- So, you say, "but we do want to connect to a public X.25 network." In
- that case, the United States has a thing called "Shared DNICs," which was
- set up by the FCC and ANSI as part of an inquiry made a couple of years ago
- when we noticed that we were running out of numbers. Under the Shared
- DNIC principle, you get a range of X.25 numbers under your public network
- provider DNIC. Tough if you want to change providers.
-
- So, unless you have folks OUT of your X.25 network who need to make data
- connections (i.e., not PAD connections) INTO your X.25 network, I wouldn't
- bother.
-
- Now, if you were the Canadian Coast Guard, things would be different...
-
- Another possibility for you is to grab one of the "ships at sea" DNICs,
- which I've never understood what they were for, but if they apply to
- anyone, they might apply to you (look in the back of X.121 to see).
