Understanding DNS Record Types

A / AAAA Records

Map a domain to its IPv4 (A) or IPv6 (AAAA) address — the core of how domain names resolve to servers.

MX Records

Specify which mail servers, in what priority order, handle email for a domain.

TXT Records

Hold arbitrary text data, commonly used for domain verification, SPF, and DKIM.

Live DNS Query

Queries authoritative DNS in real time — results reflect the current, live configuration.

Why DNS Results Can Vary

DNS records are cached at multiple layers — your ISP's resolver, your operating system, your browser — each honoring a Time To Live (TTL) value set by the domain owner. If you need to check how a change looks from several different vantage points, pair this tool with the DNS Propagation Checker.

Key Takeaways

Six Record Types: Supports A, AAAA, MX, TXT, NS, and CNAME lookups.
Live, Authoritative Data: Queries DNS directly rather than relying on a cached third-party API.
SSRF-Protected: Domain resolution is validated before any query is issued.
