You can disable the block if a visitor has a specified IP address.

Entering IP addresses to bypass is useful when you want to prevent yourself or others in you company from being blocked. You can use wildcards or enter an IP range. This field supports both IPV4 and IPV6 addresses.

Examples:

123.156.189.110 will not block only this IP

123.156.189.50,123.156.189.100 will not block the range from .50 to .100
