That's what I thought. Although, there are millions even billions of
subscribers not many of them are connected. Managing IP range shouldn't
be a problem.

What about 3G and IPv6? In theory, 3G should be always on but from my
experience with my 3G phone internet wasn't always on.

3G internet is almost the same as GPRS, ie, go to the browser and wait
for it to connect. Obviously, the carrier is different but from TCP/IP
point of view 3G connection establishment is identical to GPRS?

Thanks for your reply...
