DNS Lookup — A, AAAA, MX, TXT, NS, CNAME Records
Free online DNS lookup: query A, AAAA, CNAME, MX, TXT, NS, SOA, CAA and SRV records for any domain instantly, with TTLs, using secure DNS-over-HTTPS.
What each DNS record type does
A and AAAA records map a domain to its IPv4 and IPv6 addresses. CNAME aliases one name to another. MX lists the mail servers for the domain. TXT holds arbitrary text — most importantly SPF, DKIM and DMARC email-authentication policies and site-verification strings. NS names the authoritative nameservers, SOA carries zone metadata, CAA restricts which certificate authorities may issue for the domain, and SRV locates specific services.
Queries run over encrypted DNS-over-HTTPS directly from your browser. The TTL column shows how long resolvers may cache each answer — see what TTL means, and read how DNS works for the full picture.
Frequently asked questions
Why do results differ from what my ISP resolver returns?
This tool queries Google Public DNS. Records mid-migration can appear different across resolvers until old cached answers expire — that's TTL-driven cache draining, often mislabelled 'propagation'.
Can I look up PTR records here?
For IP-to-hostname lookups use our dedicated reverse DNS tool, which builds the special .arpa query name for you automatically.
