44.x.x.x is part of the Internet's addressable space. If we don't use it in that way, we may as well turn it back and just use 10.x.x.x
The same rationale would and should apply to companies like GE. They have 3.x.x.x/8 and they use them internally, not just the Internet facing hosts, but every host in their system. Then they pile VLANs on top of the same hardware and run 10.x's all over for "security" or "legacy" purposes.It makes no sense to me to see them using net 3 for hosts that are behind firewalls and proxies or which are never intended to be reachable from anywhere outside their systems.
Exactly how do big corporations interconnect their islands of facilities? Isn't their topology exactly like the one we face?
