What is the difference between dns and dnssec? Print

DNS (Domain Name System) is a hierarchical and decentralized naming system for computers, services, or other resources connected to the Internet or a private network. It translates domain names, which can be easily remembered by humans, to the numerical IP addresses used by computers to communicate with each other. You can think of it as the address book of the internet.

DNSSEC (Domain Name System Security Extensions) is a set of security extensions to DNS that provide authentication of DNS data. It uses digital signatures and public-key encryption to verify the authenticity and integrity of DNS data received by a DNS resolver. Basically, it adds a layer of trust to the address book to say that the data you are receiving is authenticated.

In summary, DNS is a system that translates domain names to IP addresses, while DNSSEC is a security extension to DNS that helps protect against certain types of cyber attacks by adding a layer of authentication to DNS data.
