When will ipv4 addresses run out?

Question

Computer networks

The question is rather for hosters, if regional registrars run out of ipv4 addresses and give out just a little bit, then where do they get them from? Is the secondary market really that huge, or have all hosters stocked up for years to come? When hosters will really run out of them, do you have any forecasts?

Answer 1

Yes, the secondary market is huge - formally everything has already been distributed, but there are many unused ones.

Answer 2

They have long since ended. All have owners.

Answer 3

will end tomorrow at noon.
but they say that they will bring more on Monday.
