Setting up a Dynamic DNS synthetic record

1. Click My domains in the navbar and then click your domain name.
2. Click the DNS tab .
3. Scroll down to Synthetic Records.
4. Select Dynamic DNS from the list of synthetic record types.
   
5. Enter the name of the resource you plan to have assigned a Dynamic IP, either a subdomain or @ for your default domain (“root domain” or “naked domain”).
   
6. If you selected sub-domain, enter the name of the subdomain.
7. Click Add.
8. The Dynamic DNS record is created in your list of synthetic records. Click the expand triangle to the left of the record to view its values.
   
9. Click View Credentials to view the user name and password created for this record.
   
10. Note the username and password created for the synthetic record. You will need these to configure your gateway or client software to contact the Google name servers.
    
11. You can edit or delete the record with the Edit and Delete buttons next to the record.

Tip: Directing a wild card (*) to a dynamic resource: 

While you cannot use a wildcard in a Dynamic DNS record, you can direct a wildcard to your naked domain or a particular subdomain with a CNAME record.

1. Create a Dynamic DNS record for your naked domain using @ (@.example.com) or for the subdomain you want your wildcard redirected to.
2. Create a CNAME record redirecting * (the wildcard) to your naked domain or subdomain. See Resource records for help with creating a CNAME record.

About Google Domains Dynamic DNS

Dynamic DNS allows you to direct your domain or a subdomain to a resource that is behind a gateway that has a dynamically assigned IP address. To use dynamic DNS with Google Domains you set up a Dynamic DNS synthetic record. This synthetic record:

Sets up an A record for your domain or subdomain that lets the Google name servers know to expect a dynamic IP.

Generates a username and password your host or server will use to communicate the new IP address to the Google name servers.

Once you set up the Dynamic DNS synthetic record, you must set up a client program on your host or server (the resource behind the gateway) or on the gateway itself that detects IP address changes and uses the generated username and password and communicate the new address to the Google name servers.
Note: Dynamic DNS only works with IPv4 addresses. IPv6 addresses are typically not dynamically assigned.
