When you want to forward your naked domain (example.com) to another server (www.example.com), you will need to change the domain's A records. This also means when you want to forward your URL to a Google Site, you'll need to point your A record to Google servers instead of your existing servers.
You modify A records using the administration tools available from your domain host, not the Google Admin console. The basic steps below are applicable to all domain hosts. See your domain host's support documentation for specific instructions on using the host's tools.
To change A records:
- Sign into the domain host's administrative console for your domain.
- Locate the page on which you may update the domain’s DNS records.
The page will likely be named something resembling DNS Management, Name Server Management, or Advanced Settings.
- Locate the A records for your domain. You likely have one or more A records resembling:
Name/Host/Alias Time to Live (TTL) Record Type Value / Answer / Destination Blank or @ 86400 A 126.96.36.199
- Optionally, adjust the Time to Live (TTL) to 300 seconds for every A record if possible. This signals name servers across the internet to check every 300 seconds whether you updated this DNS record. This allows you to apply changes to your DNS records much quicker.
- Update the values for the A records with the IP addresses listed at A records values. Create new A records if necessary to include all of the IP addresses in the table.
- Save your changes and wait until the changes take effect.
Please note it may take up to 72 hours before changes are propagated, depending on the TTL configured for your A record.
If you have difficulty, first try to troubleshoot A records. Then contact your domain host for assistance.
