I have a number of Linux servers (dedicated and VPS) with their own fixed IP addresses.
I would like to be able to acquire a set of long-lived IP addresses that could then be assigned to the servers in a manner of my choosing (and to new servers in the future).
My thought is that this would be a service provided by (major) ISPs - IP addresses that they could route as part of their network ops.
Do such services exist? What are they called
(I realise that I could do this with a dedicated server and some proxy setup, but a service would be better)
Thanks for thoughts!
