Domain Name System (DNS) is the Internet’s system for converting human-readable domain names into numeric IP addresses and vice versa. As an example, when a Web address (URL) is typed into a browser, DNS servers return the IP address of the Web server associated with that name. In this made-up example, the DNS converts a URL such as www.company.com, into an IP address, e.g. 192.168.8.51.
So what is the managed DNS model? Managed DNS is a where a customer utilizes authoritative DNS servers hosted by a service provider to store their authoritative DNS records and enable Internet access to their website.
