Will it do IPv6 ?
Given that they are very quiet on the IPv6 front - other than announcing that they are shutting down the only gateways that supported it for a trial - one has to wonder whether this will be a 20th century network ? Someone should tell them that the 21st Century started nearly 16 years ago !
I've been with them for some time, since my local exchange got ADSL and they had the best deal (and a fixed IP option). This (lack of IPv6) could be the final straw for me.
Even their parent BT, and Sky, both offer IPv6 as standard now.
