If you are using Windows and have not installed a "complete" security suite for the operating system, you are likely using Windows Firewall to protect the operating system.
While there are standalone firewall applications as well, or hardware firewalls, it is likely that most users make use of the built-in firewall of the operating system.
Configuration of the firewall is not as straightforward as it can be, considering that you first need to find out how to open it, and then work your way through the menus that it makes available.
The guide that you are reading looks at one advanced configuration option: how to block IP ranges in the Windows Firewall. This is a list of IP addresses that you combine in a single expression, for instance 126.96.36.199 - 188.8.131.52 which covers all IP addresses in that range. Note: the screenshot below shows a different rule.

Edit or Remove the rule
You can edit or remove the rule at any time. To edit it, double-click on it in the firewall controls and use the tabs to make modifications to the rule set.
To delete it, simply select it and hit the delete key on your keyboard afterwards. All you need to do then is confirm the prompt and the rule gets removed from the system again.Advertisement
