On GoDaddy, use the “Forwarding” feature to setup a forward from yourdomain.example
to www.yourdomain.example
. The forwarding feature can be accessed in the Domain Manager at the bottom of the “Domain Information” section:
If you do this then all traffic to yourdomain.example
will be routed to the Heroku app CNAME (which is the better approach).
One note, however, if you are on the Cedar stack then don’t use proxy.heroku.com
for the host of your www
CNAME. Instead use your-app-name.herokuapp.com
. These details are covered here.
GoDaddy also specifies that in order for your domain name to forward, its A record must be pointed to 64.202.189.170
or must fall between the following ranges: 50.63.202.1
– 50.63.202.31
or 184.168.221.1
– 184.168.221.31
.
