Everything About DNS Lookups
This free DNS lookup tool shows the DNS records configured for any domain, right in your browser. No need to open a terminal and run dig or nslookup — just type a domain and instantly see its A, AAAA, CNAME, MX, TXT, NS, and SOA records. Queries go through Cloudflare's DNS over HTTPS (1.1.1.1), so results are fast and authoritative.
If you have just migrated a website or pointed a domain at a new host, check the A/AAAA records to confirm they resolve to the right IP. CNAME records are what connect custom domains to services like GitHub Pages, Vercel, or Cloudflare Pages, and this tool lets you verify the setup seconds after saving it. The Lookup All button queries all seven record types in parallel, giving you a full DNS health snapshot of a domain in one click.
It is equally useful for auditing email configuration. MX records are sorted by priority so you can see which mail server is tried first, and TXT results automatically highlight SPF, DKIM, DMARC, and site-verification records with color badges. If your outgoing mail keeps landing in spam, checking that SPF and DMARC are present and correct is the first diagnostic step — and you can do it here in seconds.
Pro tip: the TTL (in seconds) next to each record is how long resolvers cache it. If you are planning a DNS change, lower the TTL in advance so the new value propagates faster. The tool also distinguishes a non-existent domain (NXDOMAIN) from a domain that exists but has no records of the queried type, so you always know exactly what is wrong. To check when a domain expires, pair this with the domain info checker.
