The Domain Name System (DNS) is the phone book of the Internet. Human access information online through domain names, like litextension.com or cartmigration.com. Web browsers interact through Internet Protocol (IP) addresses. DNS translates domain names to IP addresses so that browsers can load the Internet resources.
Your DNS settings provide the link between your custom domain name and the IP address of the network where the Server is hosting your site. When you set up a custom domain, or when the Server changes its IP address, you’ll need to get your DNS settings updated to point to the new IP address. To get your DNS settings updated, you’ll need to contact your domain name provider – the company that is hosting your custom domain name – or access your domain name account online.
