"Many vendors nowadays offer networking solutions said to be on the "bleeding edge" of technology and development. This is particularly common in the Linux community, with tools like GNOME-based WML browsers touted as leading the way. However, the singular protocol of the future that seems certain to be adopted and even more certain to cause a considerable headache for those not leading the way now is the new Internet itself -- IPv6. The Internet as we know it is based entirely around the IPv4 (Internet Protocol Version 4). This is becoming rapidly deprecated due to limitations, such as the maximum number of live hosts."
"OpenBSD 2.7 now ships with complete IPv6 support. In real world terms, this means you could feasibly operate a purely IPv6 network of OpenBSD machines, or have them participate in an IPv6 internetwork. The most common method of IPv6 implementation at the moment, however, is integration into the "6bone." This is a virtual IPv6 backbone comprised of hosts through which users can tunnel Ipv6 over IPv4. The basic premise is to facilitate IPv6 development and the existence of an IPv6 "internet" without the necessity of completely rebuilding the backbone infrastructure."
