What jobs do domain name serves have?

Domain name servers (DNS) play a crucial role in the internet's functionality by translating human-readable domain names into IP addresses, allowing users to access websites. They also provide services such as caching to speed up subsequent requests for the same domain and help manage domain name registration and resolution. Additionally, DNS can enhance security through features like DNSSEC, which protects against certain types of attacks. Overall, DNS servers are essential for directing internet traffic efficiently and securely.
