Configuring IPv4 interaction on an IPv6-only server

I have an IPv6-only virtual server. I can connect to it via SSH or use ping6, but I can’t work with IPv4. For example, get a file via wget (Network is unreachable). I have software that cannot be installed because of this, as far as I know it can work on an IPv6-only server in its installed form.

Is it possible to return the ability to interact with IPv4 without additional costs (for example, buying an IPv4 address)?

This is my first experience of interacting with IPv6 and trying to configure the network.
