[GLLUG] Setting up an IPv6 test.

[Chris Bell]

Hello,
Plusnet have told me that they will not roll out IPv6 addresses until they 
have totally run out of IPv4 addresses, so I am trying to set up an IPv6 test 
configuration with a firewall providing radvd and routing fdxx site-local plus a 
global prefix. I have been unable to contact/join the he.net tunnelbroker 
scheme and am now trying to set up a "6to4" tunnel. Can anyone please confirm 
the latest rules about the prefix configuration? Reading through lots of 
information the prefix should take the IPv4 address in Hex, ab.cd.ef.gh/n and 
the tunnel address prefix should then be 2002:abcd:efgh:n::/64 and for the 
usual IPv4 /32 this should make n=20 while my modem has provided an auto-
configured address where n=10. Have the rules for the fourth block been changed 
so that it can now have any value? I have set this to 20 for now.
I have read the RIPE NCC document "6to4 - Why is it so Bad"
Thanks for any help.
