Thanks for the replies,
The mask appears to be important for IPv4, and 6to4 relies on external 
gateways, so I was not sure whether the mask details were important.
I just want to get a test setup working on IPv6 before it appears as standard 
without warning, so am not too bothered about the quality of 6to4 as long as 
it works, although I aim to not break my current IPv4 setup. If and when I do 
get IPv6 I do not know whether the IPv4 address will cease immediately.
I moved to plusnet (owned by BT) because I was not receiving replies from my 
previous ISP (an entanet re-seller), plusnet worked out much cheaper for basic 
FTTC than I was paying for ordinary broadband, and I was told that they were 
about to roll out IPv6.
BT have since offered low prices, but I do not know whether their new 
customers will get IPv6. Even talk-talk offers IPv6.
I have no reason to believe any promises from these ISP's and suspect that 
problems with IPv6 on Microsoft mobile devices may be the real cause for
