Default and custom domains
--------------------------

Acquia applications come with default domains that cannot be redirected or changed. For custom domains, you can manage them through your application with domain management access. Use `.htaccess` to create redirects in your application for vanity URLs.

Updating DNS records for custom domains
---------------------------------------

After you’ve added custom domains to your Cloud Platform application, you must update the DNS records for those domains with your DNS provider before your website can serve content to visitors.

You can view the recommended DNS settings for a selected environment on the **Domains** page. If the **Domains** page displays a CNAME, configure all custom domains on the environment with the CNAME record (including bare domains if supported by your DNS provider). If the **DNS Information** section doesn’t display a CNAME, or if your DNS provider doesn’t support CNAME records for bare domains, configure any A record entries for your domains to all listed public IP addresses.

For example, if your application’s bare domain name is `example.com` and your public IP addresses are `123.123.123.123` and `123.123.123.124`, you must configure two A record entries for `example.com`; one for `123.123.123.123` and another for `123.123.123.124`.

Note

Some environments have only a single, public IP address.

Custom domains should not be pointed to any endpoints that are not listed in the DNS section of the Domains page, as this can cause unpredictable results or even downtime during platform maintenance events.

Note

Acquia doesn’t offer reverse DNS services.

Changes to DNS records
----------------------

If you have an existing application and decide to upgrade to Shield, both your DNS records and any EIPs assigned to your application infrastructure will change. IP addresses can’t move into or out of a [virtual private cloud (VPC)](/node/55887#virtual-private-cloud).

As a result, when you configure your application in Shield, you must point the DNS records of your application to the new IP address in the [VPC](/acquia-cloud-platform/architecture#cloud-vpc). For more information, see [Shield](../../../shield.html).
