About This Tool
Look Up DNS Records for Any Domain
The DNS Lookup tool shows the live DNS records for any domain name. Type a domain, pick a record type, and click Look up to see the current records with their TTL values. It supports A, AAAA, CNAME, MX, TXT, NS and SOA records.
Queries run from your browser over encrypted DNS (DNS-over-HTTPS), and Trencada never stores the domains you look up. It is perfect for troubleshooting email delivery, verifying domain setup and learning how DNS works. The tool is free and needs no signup.
How to Use the DNS Lookup
Three steps to live DNS data.
- Type a domain: Enter any domain name, for example example.com.
- Pick a record type: Choose A, AAAA, CNAME, MX, TXT, NS or SOA.
- Click Look up: See the live records with their TTL values instantly.
What Each Record Type Means
- A and AAAA: Map the domain to IPv4 and IPv6 addresses.
- CNAME: Aliases one name to another, often used for subdomains.
- MX: Shows which mail servers handle email for the domain.
- TXT: Carries verification strings, SPF and DMARC policies.
- NS and SOA: Reveal the authoritative nameservers and zone settings.
Key Features
- Seven record types: A, AAAA, CNAME, MX, TXT, NS and SOA.
- Live results: Real current DNS data, not cached guesses.
- TTL values: See how long each record is cached.
- Encrypted queries: DNS-over-HTTPS keeps lookups private.
- No logs: Trencada never stores the domains you look up.
Frequently Asked Questions (FAQ)
Is the DNS Lookup free? Yes. It is completely free with no signup.
What is a TTL? Time To Live. It tells resolvers how long to cache a record before checking again.
Why is my MX lookup useful? It shows where a domain's email goes, which is the first step in fixing delivery problems.
Are my lookups private? Queries use encrypted DNS-over-HTTPS, and Trencada never stores the domains you check.
How fresh is the data? Results come from live DNS queries, so they reflect current records.
Can I look up any domain? Yes. Any public domain name works.
