Block Access to Specific Websites

Use Windows Firewall to Block Domains

Block access by creating outbound rules.

Steps:

1. Open Windows Defender Firewall with Advanced Security

2. Go to Outbound Rules > New Rule

3. Select Custom, then click Next

4. Under Program, select “All programs”

5. Under Protocol and Ports, click Next

6. Under Scope, in the Remote IP addresses, choose “These IP addresses”

7. Add known IP ranges for the services (not always reliable as they change).

8. Under Action, select Block the connection

9. Name the rule, e.g., “Block Facebook”

⚠️ These services use CDNs and rotating IPs, so manual blocking via IPs may be incomplete unless a dedicated firewall/proxy is used.
