Is there a reason why certain companies get to retain their originally allocated Class-A netblocks with their 16 million addresses? http://www.aturtschi.com/whois/neta1.html http://www.aturtschi.com/whois/neta1.html Even companies that were given Class-B netblocks with about 65,000 addresses seems a bit wasteful. I remember when I started an ISP in 1996 it was like pulling teeth to get a Class-C with 255 addresses but there Ford sits with 16 million of their own.

Yes: those netblocks belong to them and you can't take their stuff just because you like the look of it. There aren't enough addresses in v4. Reclaiming one or two /8s here or there won't fix that. Before IANA runout in 2011, we were going through over one /8 per month, and demand has only gone up since then. Those class Bs you're so worried about would last the internet maybe 2 hours each. You can push as many allocations around as you like, but there just plain and simply isn't enough v4.
