Troubleshooting Problems With Your CNAME Record

If you've waited a few days and are still experiencing issues with changes to your CNAME records, you can quickly verify your CNAME record by running a CNAME lookup using MxToolbox:

  1. Navigate to http://www.mxtoolbox.com/CNAMELookup.aspx .

  2. Enter your tracking domain's URL in the Domain Name field.

  3. Click the CNAME Lookup button.

The image below shows the result you're after, as it shows that the domain ui.net.ingenioustechnologies.com (for a real-world example) is correctly pointing to ingenioustechnologies-com.affex.org with a CNAME record:

These results show you:

  1. Type: The type of record created for your subdomain.

    • If your DNS settings are correct, you will see CNAME in this field.

    • If you do not see CNAME in the response and only see A (or AAA) then there may be an A record in your DNS that is overriding your CNAME Record.  This A Record will need to be deleted or changed because you cannot have an A Record and a CNAME record created for the same subdomain.

    • Domain Name

      • The domain name you searched

  2. Canonical Name: The host to which your domain points.

    • If your DNS settings are correct, you will see the hostname of the CNAME target you got from Ingenious

    • If you see a different value, you will have to edit the host (or points to) value of this subdomain in your DNS settings to be the one Ingenious gave you.

  3. TTL – Time To Live: How long it will take in minimum for your entry to work. This is the amount of time your server holds on to older cached information before it refreshes to show any new changes. If your custom domain does not seem to be working properly, you may just need to wait the amount of time indicated before your custom domain will work.
