DNS Lookup
Check DNS records for any domain name instantly
DNS Records Lookup
Query DNS records for any domain — A, AAAA, MX, CNAME, TXT, NS, SOA, and more — directly from your browser using live DNS resolution. No command-line tools required.
DNS Record Types Explained: A, MX, TXT, CNAME and Beyond
The Domain Name System (DNS) is the internet's distributed phone book, translating human-readable domain names into IP addresses and other machine-readable data. DNS is hierarchical: root servers know where TLD servers are; TLD servers (.com, .org, .net) know where authoritative name servers for each domain are; and authoritative name servers hold the actual records for that domain.
Each DNS record type serves a different purpose. A records map domain names to IPv4 addresses; AAAA records to IPv6. MX records specify which mail servers handle email for a domain and their priority ordering. CNAME records create aliases from one domain name to another — useful for pointing subdomains to CDN hostnames. TXT records carry arbitrary text data, widely used for domain ownership verification (Google Search Console, email authentication via SPF/DKIM), and structured data like DMARC policies. NS records specify the authoritative name servers for a domain. SOA (Start of Authority) records contain administrative zone data including the primary name server, responsible party email, and zone serial number.
Our tool sends DNS queries directly from your browser via DNS-over-HTTPS (DoH), bypassing your local resolver and returning live authoritative data so you see current records — not cached values from your ISP's resolver.
Verify DNS propagation after changes
Check whether updated DNS records have propagated to public resolvers after making changes to your domain configuration.
Debug email delivery issues
Inspect MX, SPF (TXT), DKIM, and DMARC records to diagnose why email from a domain is being rejected or spam-filtered.
Audit domain security configuration
Check for DNSSEC signatures, SPF record coverage, and DMARC enforcement policies across your domains.
Investigate unknown domains
Look up NS, SOA, and A records to identify who hosts a domain and which registrar/DNS provider manages it.
- 1
Enter the domain to look up
Type the domain name you want to query — for example, 'example.com' or 'mail.example.com'. You can query any publicly resolvable domain.
- 2
Select the record type
Choose which DNS record type to retrieve: A, AAAA, MX, CNAME, TXT, NS, SOA, PTR, or ALL to retrieve every available record type in a single query.
- 3
View DNS records
Results display each record with its type, TTL value, and data. Multiple records of the same type (like multiple MX entries) are listed with their priority values.
All major record types
Queries A, AAAA, MX, CNAME, TXT, NS, SOA, PTR, CAA, and SRV record types covering the full spectrum of DNS configuration scenarios.
DNS-over-HTTPS resolution
Uses DoH to bypass local resolver caches and return fresh, authoritative data — not stale ISP-cached results.
TTL display
Shows Time-To-Live values for each record so you can assess cache propagation delay after configuration changes.
Bulk record type query
Query ALL record types simultaneously to get a complete picture of a domain's DNS configuration in one operation.
