UK IPv6 Experimental Service Connectivity
As the roll-out of native IPv6 dual-stack services on JANET and the
core BARs happens, a number of universities will begin to have the
option to gain native IPv6 connectivity.
Some universities, e..g those in regional networks without native IPv6
support yet,
will rely on tunnelled IPv6-in-IPv4 links until the MAN
production networks transition to support native IPv6.
The basic topology for sites connecting via tunnels features a single
core router managed at ULCC. The service offers /48-sized site
network prefixes to universities whether they use native or tunnelled
connectivity.
Where possible, native IPv6 connectivity is being used, but it is
likely that initially most new sites will be connected via IPv6-in-IPv4
tunnels, either manual or 6to4.
The end-site perspective:
A tunnel broker service will also be deployed in due course to assist
individuals seeking IPv6 connectivity at UK academic sites.
