I went to a client site a few years ago. They were a manufacturer of telco gear. Thousands of people at the location I went to.
When they first told me all their IPs were public, I tried to explain NAT and that surely they were using public IPs for everything.
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.
It's all publicly available you know. The whois databases have it all.
