What is the simplest answer to host a subdomain (only, not the main domain) on Heroku?
I tried question Config Subdomain to point to heroku app but the Heroku KB pages it points to are gone (404)
For my specific case, I want to point dev.example.com to Heroku
I do not have direct access to the DNS for example.com, it is managed by an IT person. I want to get it right the first time because it takes days for their IT person to update the DNS.
So, would it be my-app-name.heroku.com for a CNAME or proxy.heroku.com ? or something else?
