IP address blocking is commonly used to protect against brute force attacks and to prevent access by a disruptive address.

Server configuration: The server's configuration can be set to prohibit access to certain files, directories, or areas of the website.
Geo-blocking can be circumvented.When IP address-based geo-blocking is employed, virtual private network (VPN) and anonymizer services can be used to evade geo-blocks. A user can, for example, access a website using a U.S. IP address in order to access content or services that are not available from outside the country.
