I still have my Old ADSL2 connection since we had Full Fibre with another isp some years ago as a backup.
I have a /29 block of fixed IP's with the ADSL2 connection, been looking to upgrade it to full fibre and getting rid of the other fibre connection after a period of time to make sure it was working ok.
I am getting no sense from the ADSL2 isp support. !
It looks like they are removing my emails with them at the end of the year although I have had nothing official yet. ?
I have asked if I will keep my /29 IP's
They say I will loose them as I would be with another supplier

I thought the /29 block would belong to them not another supplier and if I upgraded with them I would still keep them.
