I'm currently learning about CIDR, subnets and IPv4 classes.
I understood that IPv4 classes were used to route traffic in the beginning but nowadays we use "dynamic" subnet masks with the CIDR notation.
Let's say I'm a big corporation in Russia and I need about 2 millions IP addresses for my company's network. I go to the RIPE and ask them while justifying my need. They proceed to give (sell?) me the IP address
220.127.116.11/11 which grants me usage of the IP range
18.104.22.168 - 22.214.171.124.
Assuming all I said before is correct, what steps exactly does the RIPE takes to concretize this new ownership?
My guess is that they operate the "big boys" servers that route traffics on a regional basis and will update the routing table to forward everything falling into
126.96.36.199/11 to our servers but how do they do that?
For such a big address pool I assume we don't go trough an ISP so how do they know which router to forward traffic to? Do we... physically plug our router into themselves? I'm confused...
As I'm still learning, if I said something that was incorrect, please tell me.
