WebApr 7, 2024 · DNS stands for Domain Name Service. This service allows us to access a node by its name. By default, nodes use IP addresses to identify each other on the network. DNS service allows us to map a name to an IP address. When we access a node by its name, the DNS service translates the name into the IP address. Let's take an example. WebDNS is a database that includes a website's domain name, which people use to access the website, and its corresponding IP addresses, which devices use to locate the website. DNS translates the domain name into IP addresses, and these translations are included within the DNS. Servers can cache DNS data, which is required to access the websites.
