Add a CNAME record (host-specific steps)
When using Google Cloud services, you might need to add a CNAME record to your domain's DNS settings to customize a web address, verify domain ownership, or reset your administrator password. You add and manage CNAME records using the administrative tools at your domain host, not your Google Admin console. Find your domain host below for the exact steps. If you’re not sure who your host is, see Identify your domain host.
