 Warning

1&1 does not support adding multiple AAAA records for IPv6 traffic which can negatively impact performance, especially on mobile devices. We recommend transferring DNS services to a provider that supports more than one IPv6 record per domain.

Before You Begin

Be sure that you have a:

Configure DNS Records on 1&1

A/AAAA Records

  1. Click Domain Center from the Domains panel.

  2. Click the down arrow to the right of the domain you want to point to Pantheon, then click Edit DNS Settings.

  3. Click the Other IP address option from the IP address (A Record) menu.

  4. Enter the A record value provided by Pantheon in the IPv4 Address field and either of the AAAA record values in the IPv6 Address field.

    Pantheon provides two AAAA records for improved uptime and reliability, however 1&1 only supports one IPv6 record per domain. If you'd like to add both AAAA records, then consider transferring your domain or name server to another DNS host.

  5. Click Save.

A Record for subdomain

An A record is required to configure a subdomain (e.g., www.example.com).

  1. In the Domains section of the Control Panel, next to your desired domain, click on gear symbol under Actions and select DNS.
  2. Click Add record and select the A type.
  3. In the Host name field, specify the desired host (e.g. www).
  4. In the Points to field, enter the desired IPv4 address (e.g. 23.185.0.2).
  5. Click Save.
