Block Netflix Domain Names Addresses
Once you’ve set up the OpenDNS, navigate to the Settings tab and click on IP address to access the network settings.


These domains act as a wildcard (*.netflix.com) to block connection to all the sub-domains like api-global.netflix.com, www.netflix.com, etc.
Netflix Stop Working on Router
Please allow OpenDNS a few hours to make the changes live. The blocking Netflix setting will propagate on the router connection and stop internet access.
