Re: [Info] Enterprise IP Addressing Scheme

I'd imagine most of the big companies that do this, do it because of legacy reasons. (e.g. "because we've always done it like this")

But that said, now that the pool of available IPv4 address space has been exhausted the RIRs like ARIN are cracking down on companies with existing allocations which are not, in fact using them. So some companies will look at it as a use-it-or-lose-it proposition.
