DNS

DNS stands for Domain Name System: the internet’s phone book. It turns a human-readable domain (like bitskingdom.com) into the numeric IP address of the server where your site lives.

When someone types your domain, their device asks DNS resolvers where to go. Records point the name to hosting, email, or other services. If DNS is wrong or down, the site can “disappear” even when the server is fine — because nobody can find the address.

A real-life example of DNS

You don’t memorize a friend’s GPS coordinates; you look them up by name. DNS does the same for websites. Change hosting providers, and you update DNS so the old name points to the new building — like updating a contact card after a move.

DNS is also a frequent target in outages and attacks, which is why providers and contingency plans treat it as critical infrastructure. Choosing a domain is step one; connecting it correctly is step two — see how to choose a domain name and what happened in a major Cloudflare outage.
