NUVEW Web Solutions is here to provide the answers you need. We want to demystify DNS so you can learn its importance for your business. To discuss your digital marketing strategy, give our web development team a call.
What Is DNS?
DNS, or Domain Name System, determines how your domain name—the .com address for your website—is used. Think of DNS in terms of a router, which tells everything where it needs to go. DNS translates a domain name into an IP address so that a browser can load a webpage. As a result, people don’t need to memorize IP addresses, which contain a string of numbers and decimals.
DNS converts a hostname into an IP address that a computer can read. Every internet-connected device has an IP address, and it is needed to find the correct device, similar to how a stress address lets you find a specific house.
The Four DNS Servers That Load a Website
- DNS Recursor. As the first server in the process, the DNS recursor’s role is to identify and query all servers until it recognizes the correct IP address. Consider a postal worker looking for a specific address: he or she must narrow down the correct location from the city to the street to the address number.
- Root Name Server. The next step of the process is the root name server, which represents an entire web server that has many sites. Think of it as the general location of an IP address and where the website “lives.”
- TLD Name Server. The top-level domain (TLD) name server identifies the final portion of a hostname, such as a .com extension and the last part of an IP address.
- Authoritative Name Server. Essentially, the authoritative name server sends the entire IP address to the recursor, which then displays a website in the browser.
The DNS query will complete each step before it resolves, which sometimes takes several times. That’s why there are many places in the chain that can make a query fail—which we experience as an HTTP error.
Can I Change My Nameservers?
The DNS system makes it possible for a business to transfer its website without having to change its domain name. The ideal scenario is to register your domain with the provider who hosts your website. That way, you can transfer your domain name without having to change nameservers. By changing nameserver records, you will change your DNS provider, too.
