We use cloudflare. If you look up the IP address for your public domain name, you will get the cloudflare IP, yes. If you lookup the IP address of the CNAME target, you will get the heroku IP.

on Cloudflare do you create A records (with found IPs) with name "www" or "mydomain.com"? also do you make that A record proxied or no? Thank you!

For my domain (https://www.poof.io), it's www.

If you just use something like https://poof.io, then it would be @. Depends on your site.

There should be a few historical IP addresses, but you would create an A record for each of them.

Use an A record and type in @. Proxied is fine.
