Question IP addresses shared vs dedicated

[Azurel]

I have a new server with CentOS 8.2 and Plesk Obsidian installed. In Tools "IP Addresses" there is IPv4 as type "shared" and OPv6 as type "dedicated". Why have not both the same type?

More info What is the difference between Shared and Dedicated IP addresses in Plesk?

A shared IP address refers to the use of the same IP address by multiple companies or email senders on the same mail server. A dedicated IP address, on the other hand, is only used by one sender at a time. It's the IP address from which just one individual or corporation sends emails.

"companies" is misleading, I'd say "domain names".

To answer the original question, though a bit late:
Usually you get one IPv4 address with a server because they are a very limited resource nowadays. So unless you spend extra money to get additional addresses, you'll have to share this IP for all domains and services.
With IPv6, there is no such scarcity, so you usually get a subnet that is bigger than the entire address space of IPv4. Which means it makes no sense to save address space by sharing IPs, and you could give every file on your storage its own dedicated IPv6 address if you wanted to.
