Configure DNS Records on Gandi

A Record

  1. Navigate to the domain's management page and click Edit the zone.
  2. Click the Add button and select A from the type dropdown menu.
  3. Select desired Time to Live (TTL).

    Time to Live (TTL)

    The TTL dictates the lifespan of a DNS record; a shorter time means less time to wait until the changes go into effect. TTLs are always set in seconds with a few common ones being 86400 (24 hours), 43200 (12 hours), and 3600 (1 hour).

    When you make a change to the TTL of an existing record, you need to wait for the old TTL time to pass - that is, if it had been set to 86400, you would need to wait a full 24 hours for the new setting to begin propagating everywhere.

  4. Enter @ in the Name field and enter the A record value provided by Pantheon in the Value field.

  5. Click Submit.

AAAA Records

  1. Click the Add button and select AAAA from the type dropdown menu.
  2. Select desired Time to Live (TTL).
  3. Enter @ in the Name field and enter the first AAAA record value provided by Pantheon in the Value field.
  4. Click Submit.
  5. Repeat steps 1-5 for the second AAAA record value provided by Pantheon. There are two AAAA records for improved uptime and reliability.

CNAME Record

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

  1. Click the Add button and select CNAME from the type dropdown menu.
  2. Select desired Time to Live (TTL).
  3. Enter www in the Name field and enter the CNAME record value provided by Pantheon, followed by a . (e.g. live-example.pantheonsite.io.) in the Value field.

    Note

    Remember to add the dot (.) at the end of the Value line. Hostnames without a . at the end will be suffixed by the current domain.

  4. Click Submit.

  5. Click the Activate this version button.
