About DNS records
DNS turns human-readable names like example.com into the IP addresses that browsers and apps use to connect. A and AAAA point to web servers, MX points to mail servers, TXT carries verification and policy strings (SPF, DKIM, DMARC). NS records show which authoritative servers a domain delegates to.
Common use cases
- 1Confirm your mail server config — check MX, SPF (in TXT) and DMARC records before pointing newsletters or transactional email at a domain.
- 2See where a site is hosted — A and AAAA records reveal Cloudflare, AWS, Google Cloud, Hetzner or a smaller provider, useful when debugging speed or geographic issues.
- 3Verify a domain migration — after switching DNS providers, query NS records to confirm your nameservers updated, and TXT records to confirm verification tokens propagated.
Frequently asked questions
Why are some record types empty?+
Most domains don't use every record type. A site without email won't have MX. A simple A-record domain has no CNAME. Empty arrays mean "no records of that type", not an error.
Does this hit my local DNS or a public resolver?+
A public resolver. We query Cloudflare 1.1.1.1, Google 8.8.8.8 and Quad9 9.9.9.9 directly — that bypasses ISP-level caching so you see the real authoritative answer.
How is this different from "nslookup" or "dig"?+
Same protocol, friendlier output. Behind the scenes we run the equivalent of `dig +short @1.1.1.1 example.com A`, then for AAAA, MX, NS, TXT and CNAME — all in parallel.
