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?

  • I don't mean to be rude but since Heroku is getting money from you why not ask them for an authoritative answer? – Martin M. Jun 08 '11 at 21:37
  • That's not rude, but not quite correct either. I haven't given them any money, and there are many other questions on here about Heroku, just following the trend. – Ivan Jun 08 '11 at 22:43

The proper thing to do here is CNAME your subdomain to proxy.heroku.com.

Let me know if you have any questions!

  • Thank you! It wasn´t quite clear from their support kb whether I needed an A record or a CNAME for a subdomain only situation. – Ivan Jun 09 '11 at 17:30
