Chris, I checked my mum's BT Fibre broadband as I mentioned to you at the
meet-up, but the results unfortunately are inconclusive.

I wasn't getting an IPv6 address but it seems quite likely to have
something to do with all the hassle my mum has had diagnosing her phoneline
issues with the BT Broadband people (rather than the BT OpenWorld people)
and them sending her 3 varieties of router which look like they are all
daisy chained together.

So just wanted to confirm I had checked but I can't help I'm afraid.
