Only traffic to/from a certain IP address is blocked when it is blacklisted. This feature in no way suspends or interferes with your hosting services for other people. Everyone else can see that your website and all of its features are working regularly.
What is an IP ban?
The setting of a network service that prohibits requests from hosts with specific IP addresses is known as IP address blocking, also known as IP banning.
[More information required] Blocking IP addresses is frequently used to defend against brute force attacks and to bar access from disruptive addresses. IP address blocking can be used to prevent access to or from a certain location, such as when content is syndicated to a location using Internet geolocation and blocking.
Using a hosts file, IP address blocking is achievable on many computers. IP address blocking is frequently implemented by TCP wrappers in Unix-like operating systems.
