What DNS does

DNS works like an address book. It turns names such as askalex.support into technical addresses computers can use.

Typical signs

A browser may say that a website cannot be found, while other websites still open normally.

Before changing DNS

Restart the browser and router first. Only change DNS settings when you have a clear reason and can undo the change.
