![]() ![]() In practice, nameserver addresses are often used to point a domain name to a hosting account via the DNS services. For example, here are Hostinger’s DNS nameservers: Hosting providers usually have two or more nameserver addresses. Whenever someone sends a query about your domain name, the nameserver will send back the necessary information of your domain name, allowing them to find your website.Ī nameserver address looks similar to a domain name. What Are Domain Nameservers?Ī domain nameserver’s job is to store all types of DNS records of a domain name. In other words, DNS caching makes it so that the next time you want to visit the same site, it will simply send back the IP address match obtained before. ![]() The recursive resolver will obtain the IP address and send it back to your computer, directing you to the site.įinally, the domain name system resolver performs DNS caching, storing IP addresses collected from authoritative nameservers as temporary data. It stores all information related to the domain name you want to visit, including its IP address. The authoritative nameserver or authoritative DNS server is the final authority in the DNS resolution process. Next, the TLD nameserver will inform the resolver about the location of the matching IP address at a specific authoritative nameserver. If your query is to find the IP address of, the root nameserver will redirect the DNS recursive resolver to the. A TLD is the far end of a domain name, such as. The TLD nameserver is a DNS server function that is responsible for storing and managing information about domain names that use a specific top-level domain (TLD). ![]() Then, it will tell the recursive resolver to go to the correct TLD nameserver. Once the root nameserver receives a request from the recursive DNS resolver, it will identify the top-level domain of the domain name. It doesn’t keep the information you’re looking for, which is the IP address to match the domain name – but it gives directions to where it can be found. The root nameserver or root DNS server is at the top of the DNS hierarchy. However, if no match is found in its cache, the DNS resolver will send the request to the next DNS server – the root nameserver. If said IP address found, the request sent to the DNS servers ends here, and you will immediately see the site you want to visit. When the DNS resolver receives a request, it will first search its cache to find a matching IP address for the domain name. Its purpose is to forward a request to other domain name system servers and then send it back once fulfilled. The DNS resolver or recursive resolver acts as the primary intermediary between a computer and other DNS servers. The following section will cover each DNS server and how they work. If your computer can’t find a matching IP address in your hosts file or cache, it will submit your DNS query or request to a network of four DNS servers. What DNS Servers Are Involved in Loading a Website? However, if no matching IP address is found in your hosts file and cache, other additional steps will be added to the DNS resolution process. Matching IP addresses for the DNS service are commonly found in your browser cache or internet service provider (ISP) cache. The hosts file is a plain text file that maps hostnames to IP addresses in an operating system, while the cache is temporary data stored by a hardware or software component. A DNS record is an IP address that matches the fully-qualified domain name.įirst, your computer will search its hosts file and cache. Next, your computer will check whether it already stored a DNS entry of the domain you submitted locally. What you’re doing here is submitting a DNS request. ![]() You want to be taken to Hostinger’s website, so you enter the domain name into the web browser’s address bar. Here’s an example of what the DNS resolution process is typically like to illustrate better how DNS works. However, this seemingly instant task consists of several steps known as the DNS lookupor DNS resolution process. When users enter a domain name into the address bar of their web browser, they will be taken to the site they want to visit. A DNS or a domain name system is used to translate domain names into IP addresses, allowing the browsers to access other internet resources. ![]()
