Block two IP address rangesUsually, you watch the video from CDN (Content Delivery Network) but not directly from YouTube. In this case, ISPs (Internet Service Providers) will throttle the connection speed from you to these CDNs. This will lead to YouTube videos load slowly. Blocking two IP address ranges for these CDNs (184.108.40.206/24 and 220.127.116.11/16) can solve the problem.
Follow steps below:
1. Open Command Prompt as administrator.
2. Enter the following command:
netsh advfirewall firewall add rule name=”YouTubeTweak” dir=in action=block remoteip=18.104.22.168/24,22.214.171.124/16 enable=yes
3. Press Enter key on your keyboard. Then the rule will be added.
4. Close Command Prompt.If you wan to remove the rule, run Command Prompt as administrator again and type the this command: netsh advfirewall firewall delete rule name=”YouTubeTweak”
