To ensure that all of the subdomains are also allowed/blocked properly, remove the “www” from domains you enter in your Block list/Allow list (previously known as “Blacklist/Whitelist” list).
- Log into your account at netgear.opendns.com, click on Account Settings, then select Block list/Allow list (previously known as “Blacklist/Whitelist” list).
- Add the domain you wish to blacklist and whitelist to the “Always block” and ”Never Block,” respectively.
- Flush your local and web browser cache afterwards:
