Before You Begin

Ensure you have the following:

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 Details.

Keep this page open and log in to your Namecheap account in a new tab before you continue.

Verify the Domain to Add HTTPS

When entering the value for the Name/Host, the bare domain and trailing dot (".") must be removed from the value provided by Pantheon. For example, the value entered in the Name/Host field for the Namecheap Advanced DNS configuration should look like _name-sample, or in the case of a subdomain, like _name-sample.subdomain where the subdomain is replaced with a specific subdomain.

After completing the fields on the page, click Verify Ownership.

Configure DNS Records on Namecheap

A Record

  1. Select Domain List then click Manage, next to the domain you want to point to Pantheon.

  2. Navigate to Advanced DNS and click Add New Record.

  3. Select A Record for Type.

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

  5. Select the 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 - for example, if it is set to 86400, you need to wait a full 24 hours for the new setting to begin propagating everywhere.

  6. Click Save changes.

AAAA Records

  1. From the Advanced DNS tab, click Add New Record.
  2. Select AAAA Record for Type.
  3. Enter @ in the Host field and enter the first AAAA record value provided by Pantheon in the Value field.
  4. Select the desired Time to Live (TTL).
  5. Click Save changes.
  6. Repeat steps 1-4 for the second AAAA record value provided by Pantheon. There are two AAAA records for improved uptime and reliability.

Subdomains

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

  1. From the Advanced DNS tab, click Add New Record.
  2. Select A Record for the Type.
  3. Enter www in the Host field and enter the A record value provided by Pantheon (e.g. 23.185.0.2) in the Value field.
  4. Select the desired Time to Live (TTL).
  5. Click Save changes.
  6. Repeat steps 1-5 for the two AAAA records.
