Configure DNS for your network

To configure dynamic DNS for your network:

  1. Sign in to Fiber using the email and password you use for your Fiber account.

  2. Select Network at the top-left corner. (If you don’t see it, click the navigation menu to display the selection.)

  3. In the settings pane, click Advanced; then click DNS.

The DNS tab enables you to to set up dynamic DNS for your network.

Dynamic DNS

The Fiber network assigns IP addresses to devices when they connect. These IP addresses are generally unpredictable and subject to change. If you want to host a service such as FTP or SSH on your network, use the DNS advanced settings to set up Dynamic DNS for the hostname, so outside consumers of the service can still access it when your host IP address changes.

You must set up a Dynamic DNS account with a third-party provider before you configure this setting. The following sites provide this service:

Dynamic DNS is coordinated by the Network Box; no special software needs to be installed on your computer.

To configure Dynamic DNS:

  1. Select the name of your Dynamic DNS provider from the Service provider drop-down menu.

  2. Enter or modify the username for your Dynamic DNS account.

  3. Enter or modify the password for your Dynamic DNS account.

    If you want to see the password, click Show to make it visible.

  4. Enter the domain or hostname for the service you want to host.

  5. Click Apply.

To stop using the Dynamic DNS service:

  1. Select None for Service in the Dynamic DNS section of the DNS tab.

  2. Click Apply.

DNS name resolution

When an outgoing request is sent from your network, the Network Box must find the IP address that corresponds to the domain name in the request. It contacts a DNS server to do this. If the DNS server does not know the mapping, the Network Box contacts the next DNS server in the hierarchy, and so on, until an IP address is found or the Network Box has checked all DNS servers in its list.

By default, the Network Box uses DNS servers specified by Google, but you can override this.

To use Google-selected DNS servers for name resolution:

  1. Click Automatic for DNS servers.

  2. Click Apply to start using Google-selected DNS servers.

To specify custom DNS servers to use for name resolution:

  1. Select Custom for DNS Servers.

  2. Enter the IP addresses of up to three DNS servers in the DNS server fields, in the order in which you want the Network Box to contact; then click Apply.

    If you specify these custom DNS servers, this becomes the complete list of DNS servers to contact, and the DNS servers are contacted in the order in which you list them. If you identify a single DNS server, it is the only server contacted.
