DNS is a global system for translating IP addresses to human-readable domain names. When a user tries to access a web address like “example.com,” their web browser or application performs a DNS Query against a DNS server, supplying the hostname. The DNS server takes the hostname and resolves it into a numeric IP address to which the web browser can connect.
The Domain Name System (DNS) is a critical infrastructure that is used to translate domain names into IP addresses, and it plays a key role in the functioning of the internet. As such, DNS is a common target for cyber-attacks, and there are several different types of threat vectors that are commonly associated with it.
