One big question concerned deployment of IPv6. For more information, check out the 6bone home page . Let's start out with what has been a major effort within the Internet Area of the IETF, and that is the new IP protocol, IPv6.
Every machine connected to the Internet needs an address.
The primary goal of IPv6 was to provide sufficient addresses for the foreseeable future. Once it was understood that the base IP packet would have to change to accommodate larger addresses, it of course made sense to also cleanup and fix known deficiencies in IPv4. Getting large amounts of address space has become quite difficult today. In contrast, IPv6 address space is almost unlimited in size. Groups looking to roll out huge numbers of devices will be attracted to the larger address space.
