Gandi.net and Heroku Domain Routing

Question

My .io domain works for www.domain.io, but not for the domain.io version. Below are each of the versions and revisions I have tried with ample time between each. I al

Answer 1

it seems that it best to redirect from the root domain to the one with www. Any other way?

As of right now, no. Unfortunately, ALIAS records are not used by Gandi, and A records are not available for use with Heroku because Heroku does not use fixed IP addresses.

The record type that both Heroku and Gandi recognize is the CNAME record, which can not be used for bare domains. Or, at least, shouldn't be used for bare domains. See https://superuser.com/questions/264913/cant-set-example-com-as-a-cname-record.

And for anyone lost, looking for how the heck to implement this, here's my cheat sheet for the work-around.

Step 1: In Gandi, set DNS zone file.

Name  Type     Value

@     A        217.70.184.38  # Gandi's server
*     CNAME    my-app.herokuapp.com.  # trailing . is required
www   CNAME    my-app.herokuapp.com.  # trailing . is required

Step 2: In Gandi, set web forwarding for the domain.

The type of forwarding will be 'direct (permanent)', leave the subdomain blank, and set the forwarding address as www.my-custom-domain.com.

Step 3: In Heroku, set Heroku custom domains.

Domain Name                 DNS Target

*.my-custom-domain.com      my-app.herokuapp.com
my-custom-domain.com        my-app.herokuapp.com
www.my-custom-domain.com    my-app.herokuapp.com
