It's not a secret that Google applications cannot work on a “naked” domain (naked domain), and for Google Apps websites you had to search for a third-party web-forwarding service or use wwwizer. Google has finally decided to correct the situation and make its own forwarding service for bare domains. The new service can redirect only to a subdomain and only from a bare domain.
To enable the service, you need to enable preliminary versions of the functions in the Google Apps domain settings and select the next generation interface. After that, the interface will become English, and in the “Domain settings” section the “Domain names” tab will appear and you will just have to click on the “Redirect your naked domain” link, select the subdomain to which the redirection will be made and make changes on the NS server. It is worth noting that Google approached the problem with the usual seriousness and in the A-record you will need to add as many as 4 IP addresses.
