What is DNS?
DNS (Domain Name System) is a kind of internet phone book. The DNS for a domain name contains a number of settings that point different aspects of the services you can get with a domain name (like a website or emails) to particular servers.
In order for your website to show on your custom domain (e.g. johnsshoesshop.com) you'll need to point the website services part of the DNS for your domain name to our servers.
You can find out how to do so by reading here.
The DNS for your domain name needs to be changed with whoever you registered your domain name with. If you need assistance in changing the DNS on your domain then you can contact us.
