Hi

I'm thinking of this question for a very long time already since i'm still a student, my exposure to corporate inter-network is still very little.

#1 Since the WAN Network carries all public ip addresses, how do IANA know who to assign the IP addresses to? I could just use one of the Live servers to obtain another company's IP address isn't it?

e.g.,
--- my company (202.132.128.100)
--- another company (218.211.29.38)

I can just steal his IP isn't it? and he'll just reiceve the conflicting ip error?

Please advise.
