What is dns traffic?

DNS traffic refers to the data exchanged between devices and Domain Name System (DNS) servers during the process of resolving domain names into IP addresses. When a user types a website address into their browser, a DNS query is sent to a DNS server, which responds with the corresponding IP address. This traffic is essential for navigating the internet, as it enables users to access websites using human-readable names instead of numerical IP addresses. High volumes of DNS traffic can indicate normal browsing activity or, in some cases, potential security threats like DDoS attacks.
