Yes, I joined Demon dial-up, but obtained my own domain name then left when 
they were sold.

I paid a single one-off £5.00 for a static IPv4 address but no IPv6 from 
Plusnet (now owned by BT), but am less bothered now as my websites and
emails are handled by Mythic-Beasts, with CA certificates, and a low total cost 
including the Plusnet charges.

A friend living in a Grosvenor Estate flat in Westminster is now delighted to 
have the output of a RaspberryPi on his 40 inch TV with full fibre to the flat 
provided by CommunityFibre at £24.00, less an agreed discount because he is 
96. He has a 192.168.0.0/16 address but I have yet to discover whether his 
IPv6 address is actually static.
