As we reported back in July, the Internet Engineering Task Force has been thinking about ways to make the IPv4 world talk to the (future) IPv6 world. This way, we don't all have to upgrade at the same ...

For the most part, the dire warnings about running out of internet addresses have ceased, because, slowly but surely, migration from the world of Internet Protocol Version 4 (IPv4) to IPv6 has begun, ...

In addition to IPv4 (often written as just IP), there is IP version 6 (IPv6). IPv6 was developed as IPng (“IP:The Next Generation” because the developers were supposedly fans of the TV show “Star Trek ...
