Upstream Servers ​

To resolve DNS queries using an alternative upstream DNS server, instead of your local or ISP's DNS server:

  • You can select either Google's or Cloudflare's public recursive DNS servers from the dropdown menu.
Google or Cloudflare DNS server options.
  • Or the DNS server can be explicitly defined by clicking on the + button, providing the server's IP address along with an arbitrary name, and clicking + Create. This will add the server as an option in the dropdown menu.

Static IP ​

Domain names can also be resolved to an IP address of your choosing by checking the Use static IP checkbox and providing the desired IP address in the Redirect to static IP input field.

Hosts ​

You can define which hosts your custom DNS configurations do/do not apply to by adding them to the Included Hosts and Excluded Hosts lists respectively.

TIP

Glob syntax (*) is supported to account for varying subdomains and top-level domains/extended top-level domains.
