Definition
A nameserver is a server that translates domain names into IP addresses, enabling browsers to locate and connect to websites. It is a crucial part of the Domain Name System (DNS), which helps to map human-readable domain names (like www.example.com) to their corresponding numerical IP addresses.
Function
The main function of a nameserver is to respond to DNS queries from clients (such as web browsers) by providing the IP address associated with a requested domain name. This process allows users to access websites using easy-to-remember domain names rather than having to remember complex numeric IP addresses. Nameservers play a key role in the overall functionality of the internet by ensuring smooth navigation and accessibility of websites.
