What I am trying to do is to display the contents of this website: https://flavioazevedo-old-rbookak.netlify.com/ on my squarespace subdomain http://www.rbook.flavioazevedo.com/ . In other words, I want to give this link to people (http://www.rbook.flavioazevedo.com) and they will see the content of this netlify website ( https://flavioazevedo-old-rbookak.netlify.com) without them knowing or being redirected towards that address on Netlify.
On the Squarespace side of things, things seem OK. https://toolbox.googleapps.com/apps/dig/#CNAME/rbook.flavioazevedo.com
I am in doubt if I should do anything on the Netlify side of things. I thought I needed this https://docs.netlify.com/domains-https/custom-domains/configure-external-dns/#configure-a-subdomain but it says nothing about configuring on Netlify.
This is my current configuration at Netlify:
I am also confused on terminology. I think what I am trying to do is “Pointing” but I am not sure.
Any help is extremely appreciated.
