I do not quite understand how ipv6 works. I can rent an address from a broker and get it through the tunnel, but in that case, I still have to work through ipv4 to begin with, right? And if my provider supports ipv6 and, for example, having received a certain white IP for my phone, by switching to another network, it will change, right, I understand? I read everything I could find on Google, but it's not very clear. More technical implementation on the part of the provider, but the user side is affected very little. Throw information for a better understanding of the subject.

Well, yes. The broker will give you a special tool that will create a virtual adapter with a white ipv6 address. At the same time, the broker will route to the address assigned to you. In real life, it is very similar to a regular tunnel (pptp, gre, ipsec). On the other hand, it is theoretically possible to use l2tpv3 or gre for these purposes. You need to select the tunnel protocol and broker for it.

And if my provider supports ipv6 and, for example, having received a certain white IP for my phone, by switching to another network, it will change, right, I understand?

Right. Although you can buy a block of ipv6 addresses and set up a bgp session with your provider. However, they are unlikely to contact individuals for these purposes.

In the described aspects, the behavior of IPv6 does not differ from the behavior of 4-ki. Those. if there is no white address, you build a tunnel to the provider and you are given a white address into the tunnel (at your end of the tunnel) (only in the case of the six you will be given a huge network of several thousand addresses, and to build such a tunnel, transport based on white 4 addresses).
With the transfer between providers, the story is the same. The difference is that you _always_ have a white address. No options (in fact, no, but in general, almost no options - white). And you can use the same mechanisms so that this address does not change from switching to another provider.
