That's how I think it should be, but Paul Graham disagrees (or at least he did in 2008 and I haven't seen anything later about him changing his mind).

In [1] he wrote:

The problem with this idea would be all the existing software, hardware and infrastructure out there. You would either need to make it an alias, which wouldn't really change anything, or you would need to update everything everyone everywhere has, which is essentially the IPv6 migration and we all know how that is going.

You already have .internal reserved, you know?

How would you express that in an IPv4 header? These address ranges serve a real purpose.

edit: OP: just like the downvote button is not for disagreement, the delete button is not for karma management. Not sure why you would respond to my post here and then immediately delete it.
