DNS lookup
Query A, MX, TXT, NS and more records for any domain — over DNS-over-HTTPS.
Resolved via Cloudflare 1.1.1.1, proxied through our server. Never stored.
How to do a DNS lookup
- Enter a host. Type a domain or host name, like example.com.
- Choose a record type. Pick A, MX, TXT, NS or another record type.
- Resolve. See the matching records with their TTLs.
About DNS records
DNS is the internet’s address book: it maps names like example.com to the servers that answer for them. An A record points to an IPv4 address, MX records route email, and TXT records hold verification strings and email-authentication policies like SPF and DKIM. This tool resolves any record type over encrypted DNS-over-HTTPS and shows each record’s TTL so you know how long it stays cached. To see who owns the domain, run a WHOIS lookup; to map an IP back to a name, use the reverse DNS lookup.
Frequently asked questions
- A and AAAA (addresses), MX (mail servers), TXT (SPF, DKIM, verification), NS (name servers), CNAME (aliases), SOA, CAA and SRV. Pick the type and enter a host.
- We resolve over DNS-over-HTTPS using Cloudflare’s 1.1.1.1 resolver, proxied through our server so nothing about your query is stored.
- DNS is cached at many layers. Public resolvers may have fresher or staler records than your ISP. The TTL shown tells you how long each record can be cached.
- Look up MX for your domain to see mail servers, then TXT to find SPF and DKIM records. For a deliverability check, use the email validator.
- No. DNS shows where a domain points; WHOIS shows who registered it and when it expires. Use both together.
