Overview

Settings apply globally to the Refract DNS application and can be configured on the Setting screen. Any changes to the settings are applied to the Refract DNS Windows Service when they are saved without requiring a restart of the Windows Service.

Settings

The following can be configured:

  • Upsteam DNS - the IP of the DNS servers that will be queried if Refract DNS cannot handle the query itself. By default Google's Public DNS is used which has IP 8.8.8.8 and 8.8.4.4.

    This is a comma separated list of IP address.

    DNS servers are queried based on the order they appear in this field. If Refract DNS does not receive a response from a DNS server within the required time limit it queries the next DNS server in the list. The order of the DNS servers is very important and should go from most local to global.

    If your company has an internal DNS server(s) you should add it to the start of this list.

    If you are unsure about the IP of your current upsteam DNS server you can click the Find button next to an active Network Interface. This will find the DNS server using the normal method use by Windows.
  • IPV4 Blacklist Endpoint - the value returned for Blacklisted A Records. The default value is 0.0.0.0.
  • IPV6 Blacklist Endpoint - the value returned for Blacklisted AAAA Records. The default value is ::.
  • Network Interfaces - a list of network interfaces that are available on the current computer.

    You can either decide to let Refract DNS automatically override your network interfaces or configure which interfaces will be overridden manually.

    Automatic override - Refract DNS will automatically override any active Network Interface. If the active Network Interface changes Refract DNS will automatically update to override the new interface. This option is suitable for most users.

    Manual override - To manually configure the network interfaces disable automatic mode. You will then see a set of toggles next to each network interface. Use the toggle next to each interface to indicate if the network interface should use the Refract DNS Windows Service . The interface that is currently active, i.e. connected to a network, will be indicated by the text (Active). If an interface that isn't overridden becomes active then Refract DNS will no longer be able to intercept DNS requests.
