UNH IPv6 Information

IPv6 the new Internet protocol

The Internet Protocol version 6, commonly referred to as IPv6, is the future of Internet communications. In the early 90s Internet Registries realized that the current address scheme would not sustain the growth of the Internet and began working on a new address design. The result was IPv6, the new standard for Internet communications with 128 bits allocated for addresses. The Internet which is currently running IPv4 (32 bits for address) only supports about 4 billion unique addresses. Today it seems that everything is Internet enabled and the prolific distribution of smartphones, tablets as well as the developing Internet of Things (IOT) current addressing will not support a robust Internet. This is where IPv6 steps in and enables support for the massive growth of the Internet offering a functionally unlimited amount of unique address space with about 340 trillion trillion trillion addresses. Implementing IPv6, if implemented properly, will keep the Internet going and growing in functionality and new exciting uses/applications.

USNH/UNH IPv6 Support

The Internet is changing fast and UNH IT is committed to providing the services our community requires to support the mission. We are actively planning, implementing and managing IPv6 services on the UNH/USNH network. As UNH moves towards IPv6 support across the network our first implementations have been in safe and controlled environments to ensure network stability and to not adversely affect current IT services. The long term goal is to transition to a fully supported IPv6 network at UNH and throughout the University System of New Hampshire. UNH is a land, sea and space grant university which is one reason it is important to keep pace with Internet standards and government mandates while providing the best possible IT services.

Transitioning to IPv6 does not mean disabling IPv4. In most cases the transition period will support both IPv4 and IPv6 on the same network. Modern operating systems typically have both IPv6 and IPv4 enabled by default and will operate together dynamically selecting the best protocol for the application. This is very similar to the days where Novell, DecNet and EtherTalk all worked on the same network alongside IPv4.

During the transition period top priority is to maintain a secure and robust network while IPv6 operates in parallel with IPv4. The transition to full IPv6 will take several years. Making steps toward IPv6 support today will not only allow a simplified network address routing structure it will also allow the Internet to develop new and more fully featured end to end applications. UNH/USNH is committed to do our part in moving the university system and the Internet into the future with new technology and possibilities.
