DNS Lookup
Enter any domain name and query all DNS record types: A, AAAA, MX, TXT, CNAME, NS, SOA, PTR. Useful for troubleshooting email, web, and DNS configurations.
Why use a DNS Lookup tool?
DNS (Domain Name System) is the phonebook of the internet — translating human-readable domain names into IP addresses and routing email, web traffic, and services. A DNS lookup tool lets you query any record type in real time, debug propagation issues, verify MX records, and inspect TXT records for SPF, DKIM, and domain ownership verification. Pair it with WHOIS lookup and IP geolocation in the networking tools category.
All record types
Query A, AAAA, MX, TXT, CNAME, NS, SOA records — or use ALL to retrieve every available record type at once.
Live results
Results are fetched in real time from public DNS resolvers so you always see the current state of the DNS zone.
Propagation debugging
Use the tool repeatedly to check whether DNS changes have propagated to public resolvers after updating your zone.
DNS record types reference
Each DNS record type serves a specific purpose. Understanding them is essential for configuring domains, email, and services correctly.
| Record type | Full name | Purpose |
|---|---|---|
| A | Address | Maps a domain to an IPv4 address |
| AAAA | IPv6 Address | Maps a domain to an IPv6 address |
| MX | Mail Exchange | Specifies mail servers responsible for receiving email for the domain |
| TXT | Text | Free-form text — used for SPF, DKIM, domain verification, and DMARC |
| CNAME | Canonical Name | Alias of one domain to another — commonly used for subdomains |
| NS | Name Server | Identifies authoritative name servers for the domain |
| SOA | Start of Authority | Contains administrative information about the zone — TTL, serial, contact |
| PTR | Pointer | Reverse DNS — maps an IP address back to a domain name |
