blocking bypass

IP address blocking or IP banning is a configuration of a network service that blocks requests from hosts with certain IP addresses. IP address blocking is commonly used to protect against brute force attacks and to prevent access by a disruptive address. It can also be used to restrict access to or from a particular geographic area; for example, Syndicating content to a specific region through the use of Internet geolocation.IP address blocking can be implemented with a hosts file (e.g., for Mac, Windows, Android, or OS X) or with a TCP wrapper (for Unix-like operating systems). It can be bypassed using methods such as proxy servers; however, this can be circumvented with DHCP lease renewal.
