Wildcard CNAME not working?

Hi !

I could see your DNS question, and I may give you a few help to check what is going on.

Using a CNAME records in DNS presumes that you are pointing to a Fully Qualified Domain Name, as it is a record used to point to Canonical Names only.

In your typical case, you are trying to point a CNAME to your domain ‘@’ which can only point an IP. As far as I know that kind of records, I would not use that kind of CNAME in my DNS zone file.

You can solve this issue in 2 ways :

• You could point the ‘www’ subdomain to the PTR record of your IP address, and match the FQDN requirements to use a CNAME in your record. The digitalocean admin panel allows you to do so once you’ve booted a container, and this could be the solution

• You could use a second A record to point your ‘www’ subdomain to the same IP as your domain. This solution is less sexy as it will need you update your DNS zone file twice each time an IP changes in your design. But this is an acceptable solution if you don’t want to fix PTR for all the containers you will create in DigitalOcean admin panel.

I hope this information could help you. Feel free to let me knows if it was OK to issue your case ;)
