How dns work and what are the different records in dns?

Question

Accepted Answer

DNS (Domain Name System) is a system that translates domain names to IP addresses to locate resources on the internet.

DNS works by translating human-readable domain names (like google.com) into IP addresses (like 172.217.3.206).
Different types of DNS records include A records (for IPv4 addresses), AAAA records (for IPv6 addresses), CNAME records (for aliasing one domain to another), MX records (for mail servers), and TXT records (for arbitrary text data).
DNS operates through a hierarchical system of servers, with the root servers at the top, followed by top-level domain servers, authoritative name servers, and caching resolvers.
DNS queries can be recursive (where the resolver asks other servers on behalf of the client) or iterative (where the resolver asks one server at a time).
