Usually, you configure the custom domain at the event level because each event has its own address.
How do I configure my domain's DNS to point to the CNAME of pages.inevent.com / pages.inevent.uk?
You can configure your domain's DNS at the company level or at the event level. Both procedures are basically the same, but when setting it at the event level, make sure to disable the Landing page feature.
For that, go to Settings > Tools > Registration > Edit and disable the Landing Pages feature.
Then, to custom a domain in the event level, go to Event > Details > Custom Domain. Press Edit and type your domain. Press End.
Then, if you click on the Information button on the left side of the Custom Domain, you will see a CNAME and the page that it has to be: either pages.inevent.com or pages.inevent.uk.
To custom a domain at the company level, go to Company > Details > Custom Domain. Press Edit and type your domain. Press End.
Then, if you click on the Information button on the left side of the Custom Domain, you will see a CNAME and the page that it has to be either pages.inevent.com or pages.inevent.uk.
It is recommended to redirect your root domain to the www domain. It means that most of the domain registers will require you to type www before you type your domain. The root domain is the one that you purchase.
As an example, you can use the Amazon web services: Console.aws.amazon.com . You could also use your desired server, such as: 1&1, Enom, Generic, GoDaddy, Namecheap, Network Solutions. In the Amazon example, click on Create Record Set > type the name > choose CNAME. In the value, add: pages.inevent.com or pages.inevent.uk and click on Create.
