You can use .htaccess to block access to your website from single IP addresses or IP ranges.
The following syntax can be used to block with:
<RequireAll>
Require all granted
# Bloker enkelt IP
Require not ip 192.0.2.1
# Bloker IP range
Require not ip 192.0.2.0/24
# Bloker IP range
Require not ip 192.0.2
</RequireAll>
And if you want to block all access except from some IP addresses:
Require ip 69.46.36.0/27
Require ip 192.0.2.1
Just add the relevant lines to the web hosting's .htaccess file.
To block selected countries, you can use this tool: https://www.ip2location.com/free/visitor-blocker
