This is incorrect; everything remains the same but you now have the option to get a cheaper instance by not getting an IPv4 address:
> "The total price for cloud servers with public IP addresses is the same as before. The only change that comes with the new network options is the ability to reduce costs by removing the Primary IPv4."
These are the three options you have:
- Two public IP addresses (IPv4 and IPv6) – The server has a public network and supports public IPv4 / IPv6 connections.
- One public IP address (IPv4 or IPv6) - The server has a public network, but only supports either public IPv4 or IPv6 connections.
- No public IP addresses – The server does not have a public network. Instead, it only is accessible within a private network and with a private IP address.
Removing public IPv4 gets you a discount of €0.50 / month on the server.
Or if you want to look at it from the other side, there are no free IPv4 IPs anymore.
The linked article shows how flexible they are: both IPv4 and IPv6, or even a server with no public interface, only accessible from your other servers in order to enhance security.
I wonder if we'll see a rise in people using a gateway server for ipv4, but use ipv6 directly. Would be nice to see ipv6 users having some benefit latency wise.
