Should the CNAME end with a . or not

Question

I'm trying to validate my dns ownership for certificate verification in AWS. AWS says, add a CNAME record in your provider with this specific CNAME name and CNAME value something.example.com. and somethingelse.soms.aws.

Both these fields end with a .

Google domain says it cannot allow a . at the end in CNAME name field. I'm wondering if I should remove the . in the CNAME value also or not? does anybody know?

AWS keeps saying pending validation - not sure if it validated and failed or it never checked for validation yet - (BAD UX, but that's a topic for another day/so-question/discussion) So I'm not sure if I first try with a . and then remove and try. Confused.

In AWS this is what I see

In Google domains this is what I see

Answer 1

Turns out that google automatically adds yourdomain.com in the end of CNAME name. so be careful and double check after you add the value.

It should only be something.example.com not something.example.com.example.com

Also google domain always adds a . to the end of CNAME value. If you added a . it will not, but if didn't add, it will add a .

Double standards between CNAME name and CNAME value fields, go figure!
