Breaking down the process of DNS resolution

DNS resolution or domain resolution is the process of obtaining a domain name’s IP address. But how does it happen? Here you have a breakdown of the process of DNS resolution, explained step-by-step.

DNS resolution.

DNS resolution, or getting the IP address behind a domain name takes many steps. The DNS has a tree structure, with different levels that are responding queries for the zones (domains) that they keep. Each server that keeps the original data for a zone is called an authoritative DNS server, and it will have the most updated information about it. The other important part of the process is the DNS resolvers. They are DNS servers that search for answers and keep them based on the data’s TTL values.
