What Are Nameservers And Their Relevance?

Nameservers are a critical component of the Domain Name System (DNS), which is essential for the proper functioning of the internet. In short, nameservers are responsible for mapping domain names to the IP addresses that correspond to them in order to find and access websites.

How Do Nameservers Work?

When you type a domain name into your browser, the browser takes the name and looks for its corresponding DNS record. This record is stored on a nameserver, which is essentially a type of specialized database server. The nameserver then translates the domain name from its original characters into a numerical IP address that computers can understand and use.

What Are The Benefits Of Using Nameservers?

Nameservers are incredibly important to the functioning of the internet, as they are necessary to ensure that users can access websites. There are several key benefits to using nameservers:

  • Ease of Use: Domain names are much easier to remember than numerical IP addresses, and nameservers make it easier for users to access the sites they need.
  • Flexibility: Nameservers can be updated to allow new domain names to be added or changed quickly and easily.
  • Network Security: Nameservers can be used to increase network security by providing additional layers of protection.


Nameservers are a vital component of the internet and allow users to access websites quickly and easily. They are incredibly important to ensure the smooth functioning of the internet, and they have several key benefits that make them essential to maintaining a secure and efficient online browsing experience. Nameservers are an integral part of the Domain Name System (DNS) which is used in the internet. They stem from the proliferation of domains. The nameserver acts as an index, linking a domain to its corresponding IP address, allowing a person to reach the website associated with that domain.

The domain name is not actually the address of the website, but a pseudonym. When a user types in a domain name, behind the scenes, the user’s computer asks the nameserver for the IP address associated with the domain. The nameserver looks up the address and sends back a response to the user’s computer.

Nameservers break the hard-to-remember IP address into subdomains, and extensions. For example, in www.example.com, “www.” is the subdomain, “example” is the primary domain, and “.com” is the top-level domain. This is why the domain name is human-readable, and easier to remember.

Having multiple nameservers enables DNS queries to be sent to a multitude of servers, instead of just one. This helps to reduce the risk of downtime if a single server fails. It also allows various hosting companies to offer services separately.

There are various types of nameservers such as primary nameservers, secondary nameservers, authoritative nameservers, reverse nameservers, and wildcard nameservers. Primary nameservers are the first and most important; it maintains the zone files and is consulted when changes to DNS records are made. Secondary nameservers are like backups that mirror the information from the primary nameserver. Authoritative nameservers provide authoritative answers and contain the actual DNS information for the entire domain. Reverse nameservers allow a domain name to be associated with an IP address. Wildcard nameservers are used to serve up default pages or direct users to certain pages depending on the URL.

In short, nameservers are an integral part of the Domain Name System (DNS). They allow domains to be broken up into subdomains, and extensions and give a user’s computer the IP address associated with the domain. They are essential in facilitating website access, and without them, the internet would not be able to function.
