Use your own domain name with Third Light

If you control your own domain name, by making adjustments to your DNS records, you could add a new entry that refers to your IMS site.

Step 1 - SSL Considerations

If your site uses HTTPS, your DNS records must point to the same address specified in the SSL certificate on your site. A mis-match may cause browsers to report a security warning.

Online tools (not provided by Third Light) exist to allow you to check your DNS records:


Entering into the form should then show that there is an association between and if you have set it up correctly.

At this point you should also be able to access your IMS site on your new domain.

Step 4 - Choose the preferred domain

When your new address has been activated, your IMS site may potentially respond on two different domain names - and

Set your preferred default by altering the settings on the Configuration > Site Options > Global Settings page.
