Renting an Ip from a provider and connecting it to a server in a data center?

Question

Computer networks

In general, at the moment 4 different providers with static ip are connected to the server.
But now we want to send the server to the data center and also rent it from the Internet provider on the subnet and at the same time retain the old ip. Is it possible to do something like that so that without a physical connection of the provider's cable, by concluding some kind of contract with him, to have his external ip addresses?

Answer 1

It's not very clear, to be honest.
Addresses that can be used regardless of data center providers are called PI addresses, they are bought immediately in a bundle from /24 and require some technical and organizational gestures (ASN registration, setting up BGP announcements). Due to the exhaustion of IPv4 addresses, things have become even more confusing, now the most realistic scenario for obtaining is a purchase on the secondary market.

Answer 2

No. More precisely, you can have them if you can't use them.
About the use of DNS names, which can be fastened to any ip, apparently not heard?

Technically, I think it is possible, but no one will fool around for your sake. Although, of course, everything will depend on how much money you bring :)
Standard - no. It was high time for you to get/buy/rent your AS.
