I have a heroku app, I bought a domain, but I don't know how to configure that domain for heroku app. My domain manager doesn't support CNAME... I think. Only that DNS manager. Did I buy what I need? I don't know much about domains and hosting...
This is heroku dashboard -> settings
UPDATE
yes, my mistake was that I tried to found CNAME records, but my domain provider doesn't suport that, I found a Free DNS service. My domain server names point to that free dns service.
