How do white addresses work within the provider's network?

Question

Computer networks

Good afternoon!

I get a static public address via dhcp from the provider. Is this address shared between me and other subscribers of the provider? If so, how is it implemented technically?
If not, then it turns out that the provider built a transparent L2 channel to my router and gave me an address from the list of purchased / received by him. When the addresses run out - will the service for buying white ip be unavailable?

Thanks everyone for the replies!

Answer 1

Is this address shared between me and other subscribers of the provider? If so, how is it implemented technically?

No. But if yes, then through NAT.

When the addresses run out - will the service for buying white ip be unavailable?

They have long since ended, but the service is still available.

Answer 2

Is this address shared between me and other subscribers of the provider?

In accordance with the terms of the contract. For example, I don’t share it with anyone, this is, in general, the meaning of the white IP service (they give it to me for free, for many years already, but it doesn’t matter)

If so, how is it implemented technically?

If it's shared, it means it's not yours :) So, it's NAT working somewhere

When the addresses run out - will the service for buying white ip be unavailable?

They ended a long time ago, but providers are thrifty :)

These are mutually exclusive options.

Address is indivisible

how is it implemented technically?

There is a pool of white addresses, there is dynamic routing, and how this carousel rotates is the provider's internal kitchen. Often everyone has their own.

It's been like that for a few years now.
