It often happens when you register a new domain name and when you try to work with it you get an error that you can’t find such a site. Or you changed the IP address for the domain to a new one, but in the browser site continues to open at the old address. This usually happens because your ISP rarely updates the DNS cache, so you have to wait from 1 to 24 hours until the domain begins to work. In this case, we recommend that you use public DNS from google. Their DNS cache is updated frequently, and they also have a tool to force the updating of records – https://google-public-dns.appspot.com/cache
To change the DNS on google, here is an example of the settings on Windows.
To do this, go to the settings of the network adapter, click on “Properties”, select the protocol IPv4 and in its properties will be an item to use the specified DNS, where you need to make an entry from google.
The Google DNS address is 22.214.171.124
