After gaining some experience in configuring IPv6 networks, and also receiving feedback from others, I’ve revised our IPv6 Allocation Scheme<\/a>. This is the document which lays out how we intend to allocate networks to departments and colleges, and other services within the University.<\/p>\n

The main difference is a change from using \/112 networks for router-to-router linknets to \/64. Yes, this is horribly wasteful, or at least it feels like it coming from an IPv4 world, but we learned a few things about compatibility with actual implementations of IPv6 which made the \/64 seem simpler, for now. There is nothing preventing us moving back to \/112 or another size later on.<\/p>\n

Also the way in which site-wide service networks such as OWL and Eduroam are allocated has changed, as we have moved their location within our IPv6 space up to the top \/46. Other than that, there is not a lot which would affect departments and colleges – the changes are mostly to aid the roll-out by the OUCS Networks team.<\/p>\n

Over the next weeks I will be lighting up more IPv6 in the backbone network, and working on our Linux firewall\/gateway server (which exists until we have a proper hardware appliance in place). We’re not yet ready to offer a customer service to departments and colleges, and work on the DNS\/DHCP system has our attention through to the summer, but after that I hope we can start to have some services hosted on IPv6.<\/p>\n","protected":false},"excerpt":{"rendered":"
