![]() A browser asks a recursive server, often hosted by an ISP, to find the right IP address, and it asks the rest of the domain name system. How does a browser know which one to ask? That’s the role of recursive nameservers. There are hundreds of thousands of authoritative nameservers on the internet. The one that knows the mapping between a site’s domain name and IP address is its authoritative DNS server it’s the definitive source of truth about that domain. The domain name system is a hierarchical arrangement of servers that fall into two broad categories: recursive and authoritative. When you type a web address or click on a link, your browser knows the site’s name, but it has to execute a nameserver lookup to find out the matching IP address.Įach nameserver is a tiny part of a vast network. ![]() The internet’s routers and switches don’t understand domain names they work with IPs. To put it another way, a contacts app maps names to phone numbers.Ī DNS server does the same for the internet, except it maps domain names to IP addresses. When you want to call someone, you search for a name, and the app gives you their number. Nameservers are the internet’s contacts app. They look like this: 198.51.100.85Ī website has a name, which is for humans, and an IP address, which is for the machines that route data around the internet. IP stands for Internet Protocol, and there are two common types of IP addresses: IPv4 and IPv6, but we’ll stick with IPv4 for simplicity. IP addresses are the unique number the internet uses to route data to its destination.We all know what they look like, a series of letters and numbers separated by periods ending with what’s called a top-level domain. Businesses use domain names to promote their sites. Domain names are the web address you type into your browser.In this article, we’re going to explore some essential DNS concepts and then show you how to configure a custom server with cPanel.īefore we wade into the deep end, let’s make sure we’re on the same page with a couple of terms: You’ll be happy to hear that cPanel & WHM makes it super easy to manage domains and even a private nameserver. Server administrators know how frustrating it is to change DNS configurations and patiently wait for them to propagate, only to find out something went wrong and the site is still unreachable. These steps are necessary to protect our software from crackers.The domain name system (DNS) is fiendishly complicated, and managing the nameservers that power it can be perplexing.
