[tech] IPv6 address space changing

[David Adam]

Hi everyone,

We have been notified by ITS that the IPv6 address allocation for UWA will 
be changing from 2001:0388::/32 (an AARNET range) to 2405:3c00::/32 
(allocated portable direct to UWA).

Consequently, the UCC's v6 allocation is changing from to 
2001:388:7094:4080::/58 to 2405:3C00:1:4200::/56 (yes, we've increased our 
allocation a bit).

Unless I can solve the source routing issues (post to ucc@ shortly), there 
will not be concurrent service to these address ranges, and therefore 
there may be some interruption in IPv6 transit (even between UCC hosts) 
when I make the changeover (probably Saturday night). I will post 
information to twitter.com/ucc_status as it becomes available, but it's 
likely that there will be things that remain broken for a while.

Thanks
