What is a DNS lookup?
DNS (Domain Name System) translates names like example.com into IP addresses machines understand. A DNS lookup queries those records. This tool uses Cloudflare's public 1.1.1.1 resolvers, among the fastest in the world.
DNS record types
- A — the domain's IPv4 address.
- AAAA — IPv6 address.
- MX — the domain's mail servers.
- TXT — text (SPF, verifications, DKIM…).
- NS — authoritative name servers.
- CNAME — alias to another domain.
