DNS issue in Google's cloud dns

Question

I have a linux instance running in compute engine with a static IP open to the public. I purchased a domain name that matches the hostname of my instance (from google domains). It's been over 72 hours and the name still wont resolve. I assume I have misconfigured or overlooked something...I just cant tell what. here is some dig output that demonstrates I can resolve it using one the google domains ns, but not 8.8.8.8

rexfitzhugh ~ $ dig @ns-cloud-d1.googledomains.com A fake.fqdn.com

; <<>> DiG 9.10.6 <<>> @ns-cloud-d1.googledomains.com A fake.fqdn.com

Not sure what I'm missing here, but thanks for your help

Answer 1

You need to add the fqdn to IP address mapping in a public hosted zone( say google clouddns) and make your registerer aware about the name-server(s) of that public hosted zone .

Also, if you can add some more details about where did you add your record and when you are resolving it using the name server ns-cloud-d1.googledomains.com is that on the machine in same project or different one .
