DNS (Domain Name System) is a hierarchical and
decentralized naming system for devices connected to the internet or
a private network. It translates domain names, which are
human-readable addresses like iptolocation.io,
into IP addresses,
which are numerical labels like 192.0.2.1 that computers use to
identify each other on the network. This process involves multiple
steps: the user's computer queries a DNS resolver, which then
contacts authoritative DNS servers to find the correct IP address
corresponding to the domain name.
