DNS (Domain Name System) translates human-readable domain names into IP addresses. It also stores records for mail servers, nameservers, and text data.

What do A, AAAA, MX, TXT, NS, and CNAME mean?

A maps a domain to an IPv4 address. AAAA maps to an IPv6 address. MX points to the mail server. TXT stores arbitrary text like SPF or verification tokens. NS lists the authoritative nameservers. CNAME aliases one domain to another.

TTL (Time to Live) is how long, in seconds, a resolver should cache a record before asking again. A TTL of 3600 means the record is cached for one hour.

What resolver does this tool use?

Queries are sent to Cloudflare DNS-over-HTTPS at 1.1.1.1, which returns standard DNS records as JSON.
