Please can anyone advise on Google domain names
My clients has bought and registered their domain through G Suite.
In Gsuite there is an option to redirect the naked domain to my treepl test site - but no options to change Nameservers or DNS
Is this correct or should I be doing something else? Sorry first time I have come across this.

G Suite doesn’t register domains directly and there are no DNS controls in G Suite itself, but during the sign-up process you can register a domain through Google Domains (or possible a connected domain partner, depending on how they sign up).
So you’d need to manage the domain via the Google Domains service ( - or the domain partner if it wasn’t through Google Domains directly.
You should then have full access to the DNS and other regular domain settings.

Wonderful thank you so much for your help Adam
