You can now blacklist IPs that start with a specific prefix.

Here's an example:
/pvpn blacklist add 0.0.0.*
> This means that IPs starting with 0.0.0.*, such as 0.0.0.1 or 0.0.0.3, will be detected.

Another example:
/pvpn (bl/wl) add 0.1.*
> This means that IPs starting with 0.1.*, such as 0.1.34.124 or 0.1.44.214, will be detected.
> On the other hand, IPs like 0.6.12.232 won't be detected
> because they don't have the same starting point.
