DNS Lookup
Query DNS records (A, AAAA, MX, NS, TXT, CNAME, SOA) for any domain.
What DNS Lookup Retrieves
Query every standard DNS record type for any domain in seconds.
All Record Types
Fetches A, AAAA, MX, NS, TXT, CNAME, and SOA records in a single query so you get the full picture at once.
Record Filtering
Filter results by record type with one click, letting you focus on just the records you care about.
MX Records
View mail exchange records and their priorities to verify email routing for any domain.
Nameservers
Identify which nameservers are authoritative for a domain — essential for debugging DNS propagation issues.
TXT Records
Inspect TXT records for SPF, DKIM, DMARC, and domain verification tokens used by email and third-party services.
SOA Records
Retrieve the Start of Authority record to see the primary nameserver, admin contact, and zone serial number.
How It Works
Three steps to look up DNS records for any domain.
Enter Domain
Type the domain name you want to query. You can use a bare domain like example.com or a subdomain like mail.example.com.
Query DNS
Our resolver queries authoritative DNS servers for all record types and returns the live results — no caching delays.
Filter Results
Use the type filter tabs to narrow down results to A, MX, TXT, or any other record type you need to inspect.

Frequently Asked Questions
Common questions about DNS records and how they work.
What are DNS records and why do they matter?
DNS (Domain Name System) records are instructions stored in authoritative DNS servers that map human-readable domain names to IP addresses and other resources. Without them, browsers wouldn't know where to send traffic for your domain. They control everything from website hosting and email delivery to domain verification for third-party services.
What is the difference between an A record and an AAAA record?
An A record maps a domain to an IPv4 address (e.g. 93.184.216.34), while an AAAA record maps it to an IPv6 address (e.g. 2606:2800:220:1:248:1893:25c8:1946). IPv4 uses 32-bit addresses and is still the most common, while IPv6 uses 128-bit addresses and was introduced to handle the exhaustion of IPv4 space. Most modern domains have both.
What are MX records used for?
MX (Mail Exchanger) records specify which mail servers are responsible for accepting email on behalf of a domain. Each MX record has a priority value — lower numbers mean higher priority. If the primary mail server is unreachable, email is routed to the next lowest priority server. MX records must point to hostnames, not IP addresses.
What is TTL in DNS and why does it matter?
TTL (Time to Live) is a value in seconds that tells DNS resolvers how long to cache a record before checking for updates. A low TTL (e.g. 300 seconds) means changes propagate faster but increases DNS query load. A high TTL (e.g. 86400 seconds = 1 day) reduces query load but means changes take longer to propagate worldwide. It's best practice to lower the TTL before making major DNS changes.
