Google Domain Configuration

Before You Begin

Be sure that you have a:

• Registered domain name using Google Domains to host DNS
• Paid Pantheon plan
• Domain connected to the target Pantheon environment (typically Live)

Locate Pantheon's DNS Values

Identify DNS values to point your domain to Pantheon:

1. Navigate to the Site Dashboard and select the target environment (typically Live) then click Domains / HTTPS.
2. Click the Details button next to your domain.

Keep this page open and login to your Google Domains account in a new tab before you continue.

Configure DNS Records on Google Domains

1. Select the Configure DNS icon within the Google Domains interface:

   

2. Scroll to the Custom resource records section.

3. Enter @ in the Host field and provide the A record value provided by Pantheon in the IPv4 field.

4. Set 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.

5. Click Add to create the record.

AAAA Records

1. Within the same section (Custom resource records), change the record type from A to AAAA.
2. Enter @ in the Host field and provide the first AAAA record value provided by Pantheon in the IPv6 address field.
3. Click the + icon to the right of the IPv6 field then enter the second AAAA record provided by Pantheon in the IPv6 address field.
4. Set desired Time to Live (TTL), then click Add to create the record.

Subdomains

Create one A record and 2 AAAA records for the given subdomain (e.g., www.example.com):

1. Within the same section (Custom resource records), select the record type A.
2. Enter www in the Host field and enter the A record value provided by Pantheon (e.g. 23.185.0.2) in the IPv4 field.
3. Set desired Time to Live (TTL), then click Add to create the record.
4. Repeat steps 1-3 for the two AAAA records.
