Custom domain connect

I purchased a domain from Netlify and would like to connect my custom domain to a web deployed on Heroku. What should I set up?
After entering my domain on the Netlify web, I added @ Alias and www CNAME in DNS recodes, and the 4 names in the name server are,,,
I went into heroku settings and added with add domain. Is there anything I should delete or add?

Which domain is this for? You will need to point the nameservers to Heroku. It sounds like you’ve done this correctly just know it might take some time to propagate and fully ‘migrate’ to Heroku I’d wait the full 48 hours if it’s not working as you intend.
