Running Out of IP Addresses
If 3G catches
on too quickly, we might be in trouble. 3G devices require unique IP
addresses. With only a finite number of IP addresses available using
the current IPv4 scheme, the next generation of IP addressing is hotly
under development. Known as IPv6 (where's version 5?), it is the protocol
mandated by the 3GPP for W-CDMA, and is an option for 2.5G and GPRS.
Japan and Europe have a year-2005 IPv6 roadmap in place. North America
has none even though nearly all the world's IP technology leaders are
in the U.S. Go figure!
