How are IP addresses assigned to servers on the Internet?

Question

linux

Hello. Actually the question is how are ip addresses assigned in the global Internet? That is, let's say in my network I can either assign ip addresses myself, or use dhcp. And in "global"? Is there a common wire to which everyone is connected and everyone sets up on the ip interface that he was given? And he can write in this way and anyone. There is literature in Russian, how is it all organized?

Answer 1

"knowledge of the theory of IP networks will help you" .........
For one thing and combining the answers of people who have already written here .... :
IANA distributes blocks of addresses to providers.
Providers prescribe blocks / networks on their routers.
When you contact the provider, it gives you the address for the server / subnet and the address of its gateway, through which you exit and come to you.
And if it is not known/clear - all central (outgoing from the provider's network) routers of all providers exchange information about networks known to them. (Therefore, the "tricks" of setting up such equipment on especially large / central nodes can lead to the complete or partial inaccessibility of entire segments of the Internet)

Answer 3

in a nutshell: addresses are divided into blocks, these blocks are distributed to providers who are already distributing pieces or single addresses to their customers

Answer 4

In a nutshell - BGP, OSPF. It's technical.
And legally - providers receive a subnet and somehow allocate addresses from it to servers.
