| IPv6 |
The present Internet is based on the IPv4 protocol. Due to limitations in IPv4 a new protocol has been developed. It is called IPv6 and is expected to come into production in a couple of years together with IPv4.
Cisco has prepared many document describing IPv6.
www.ipv6.org has compiled a list of available IPv6 software and operating systems.
www.ipv6tf.org describes the IPv6 Task Forces in the various countries.
The Danish Forskningsnet has been allocated the IPv6 addresses 2001:0878::/32.
The Danish address allocation within Forskningsnettet is described here.
A Danish IPv6 taskforce has been created.
For the 3.5 year period 2002-2005 the EU had committed funds for the development of an IPv6 network covering most of Europe. Initially it was based on 155 Mb/s links. Different types of machines and software were connected to the network in order to perform a large scale test of IPv6. The project is described at www.6net.org. Nordunet has a description of the Nordic contributions.
The Danish Forskningsnet participated in the project with a total of 3 man month. The project included a 1 Gb/s link between Lyngby and Stockholm (until June 2004 a 155 Mb/s link). The network equipment included a Cisco 12404 in Lyngby and a Cisco 7206 at the University of Copenhagen. A Gigabit ethernet over a 15 km fiber connected the two routers. The line and equipment were connected at the end of April 2002.
At the end of the project in June 2005, the CISCO 12404 was returned to CISCO. At that time Forskningsnettet had already moved the IPv6 traffic to the regular production network. The same was the case for the international traffic (Nordunet and GEANT).
The following IPv6 equipment have been installed at the University of Copenhagen (KU):
Cisco 7206 with 2 1 Gb/s, 2 100 Mb/s, and 1 10 Mb/s interfaces. Is able to run IPv6 multicast.
Several CISCO 3750. Have run IPv6 since Feburary 2005, so far IPv6 multicast is not supported.
1 HP-UX 11.11 with a 25 Mbyte IPv6 patch from HP
10 Linux-Mandriva 2007.1 and 2008
2 RedHat 4.2
4 OpenBSD 4.1
2 FreeBSD 6.2 (which includes the KAME IPv6 Multicast extensions)
2 Windows XP
NetBuilder II version 11.0 router (not yet in use)
Currently IPv6 tunnels have been established over IPv4 between 2 FreeBSD machines since they support both Multicast and Unicast. These machines may also act as routers for other machines at the individual local area networks.
KU has been allocated the IPv6 addresses 2001:0878:0100::/48
