DNS Configuration

The Domain Name System (DNS) is a distributed hierarchical naming system for computers, services, or any resource connected to the Internet or a private network. It associates the information with domain names assigned to each of the participants. Most importantly, it translates domain names meaningful to humans into the numerical (binary) identifiers associated with networking equipment for the purpose of locating and addressing these devices worldwide.

The DNS Configuration page is used to manage the DNS settings of the device.

To open the DNS Configuration page, click Settings > Network Settings > DNS Configuration.

The fields of the DNS Configuration page are explained below.

Domain Name Service Configuration​

  • DNS Enabled: Enable or disable all the DNS service configurations.

  • mDNS Enable: Enable or disable multicast DNS.

  • Host Name Settings: Choose either Automatic or Manual settings.

  • Host Name: It displays the host name of the device.

    • If the host name setting is chosen as Automatic, the host name is automatically displayed.

    • If the host name setting is chosen as Manual, specify the host name of the device.

    Note

    A host name consists of 1 to 64 alpha-numeric characters and must not start or end with a hyphen (-). Special characters hyphens (-) and underscores (_) are allowed. IE browsers won’t work correctly if any part of the host name contains underscores (_).
