A record

An A record maps a domain name to an IPv4 address. That's it—you point example.com at 192.0.2.1, and DNS resolvers know where to send traffic. Every domain that actually works on the internet needs at least one A record (or AAAA if you're IPv6-only, which you probably aren't yet). You set A records at your registrar or DNS provider. They propagate globally within seconds to hours depending on TTL. A records are the bread and butter of DNS; without them, your domain is just a name floating in the void. If you're running a website, mail server, or any service, you need A records pointing at the right IP. Bunkerdomains lets you update them instantly via our control panel or API, no waiting for support tickets. If your registrar ghosts you on DNS changes, that's a real problem—ours won't.
