[ih] A revolution in Internet point-of-view - Was Re: Internet analyses (Was Re: IPv8...)

[John Day]

I figured there must be something. Yea, ping is pretty important. But it is a huge waste of IP addresses given that most lines are point-to-point.

It would seem the vast majority of IP addresses are assigned for ping. What 90%?

Gotta be a better way. ;-)

Take care,
John

Addresses on either end or not necessary. An identifier local to the router is required to distinguish them but not an address.) Most routers are connected by point-to-point lines. But that is okay, routers assigned an IP address to the Loopback module and route on that.
