They corrected me. They had a class A as I recall. When they bought a manufacturing plant from AT&T it came with a Class-A network.

It could be Lucent. I worked there. Yes, we had a class A, meaning that AT&T had several. Now they are Alcatel-Lucent, so I suppose Alcatel has an A class network, now. -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)

It's all publicly available you know. The whois databases have it all.

The list of class A network owners may be public, but my client list isn't!

Edward Snowden might have an opinion about that :-)

As I recall they very much did not want their name listed as one of my clients. Remember I get called into sensitive situations at times.

I should think most of the time? /Per -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

This is really OT, but as I mentioned it here very briefly - this is a very interesting presentation:

Makes me almost want to go active again, though I guess I would need to convert to an HB callsign.

Amazing to think that there is an entire class A network in private hands.

Back when I was at IBM in the late 90s, I had 5 public addresses, 1 for my own computer and 4 for testing. IBM had the entire 9.0.0.0/8 block and my address was 9.29.146.147. When we started working with Ethernet, we used 8.0.0.0/8. I also had 5 SNA addresses. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
