How to map a Heroku app and a domain hosted by domainFACTORY

"bioddicted", a German web service I support, transfered domain to domainFACTORY. Since I had difficulty to read German pages with Google translator and understand the system (& interface) of domainFACTORY, I decided to write an English blog post.

You can setup your domain to your heroku app with "heroku domains:add DOMAIN" command.
Custom Domains - heroku setup | Heroku Dev Center

Next step is to setup DNS A records on domainFACTORY.

You may find "Für Profis > Nameserver-Einstellungen" in the left sidebar. It's what we need! ... Even it took some time to find this menu ;)

Remove the A record points domainFACTORY and create records point following IP addresses:

• 75.101.163.44
• 75.101.145.87
• 174.129.212.2

That's all! Wait for several hours. Eat cookies & take a nap :D

# Note: Don't mind about the setting you can do from "Allgemeines > Domaineinstellungen". If you specify DNS A-records like above, the setting through ""Allgemeines > Domaineinstellungen" won't do anything. Just wait for several hours. Since I was not so much patient, I sticked to this for few hours and was confused especially by the transfer type "Frame/header/W@P" ... After a long fight, I finally found the "Nameserver-Einstellungen" menu, could setup A-records, went for a walk and found the app worked with the domain. Woo.
