How to change your DNS.

1.1.1.1
Check that it worked
Open Cloudflare’s connection test. The resolver section should show that 1.1.1.1 is connected. If pages stop loading, restore Automatic DNS and reconnect.
Test your connection ↗What changing DNS does—and does not do
- DNS translates website names into network addresses; changing it can fix some name-resolution problems.
- DNS is not a VPN and does not hide all browsing traffic, change your location, or guarantee access to a website.
- Work, school, hotel, parental-control, and managed networks may block custom DNS. Follow the network owner’s rules.
- Only enter DNS values from a provider you trust. Never install an unknown profile or app from a message or pop-up.

Restore Automatic DNS first. If only an AB33 page is affected, check the official domain directory or contact official support.
