1. Blocking a Website via Your Router

Blocking websites at the router level is one of the most efficient ways to restrict access to certain content across an entire network. When you block websites at the router, every device connected to your Wi-Fi will be affected. This is a great option for parents and businesses alike.
How to block a website using your router:
- Access your router’s settings by entering its IP address into a browser (typically something like 192.168.1.1).
- Log in using your admin credentials (these can often be found on the router).
- Navigate to the parental control or website filtering section.
- Enter the URLs of the websites you want to block.
- Save the changes, and reboot the router if necessary.
This method is especially useful for businesses or households with multiple devices. Once you know how to block a website at the router level, you can prevent users from bypassing the block, even if they switch devices.
Benefits of router-level blocking:
- Network-wide protection
- Centralized control
- No need for individual device configuration
- Difficult for users to bypass
Potential Drawbacks:
- Some routers have limited blocking capabilities
- Requires access to router settings
- May affect all users on the network, even those who need access
