Our DNS Lookup tool allows you to query DNS records for any domain name. DNS (Domain Name System) is the internet's phone book, translating human-readable domain names into IP addresses that computers use to communicate. This tool uses Google's public DNS service to provide accurate and up-to-date DNS information. You can query various record types including A (IPv4 address), AAAA (IPv6 address), CNAME (canonical name), MX (mail exchange), NS (name server), TXT (text records), SOA (start of authority), and PTR (pointer for reverse DNS).
  1. Enter the domain name you want to query (e.g., google.com)
  2. Select the DNS record type you want to look up
  3. Click the Lookup button to query the DNS records
  4. View the results including name, type, TTL, and data
  5. Click the copy button to copy any record data

What is an A record?

An A record (Address record) maps a domain name to its IPv4 address. It's the most common DNS record type and is used to point your domain to a web server's IP address.

What is the difference between A and AAAA records?

A records store IPv4 addresses (32-bit, like 192.168.1.1), while AAAA records store IPv6 addresses (128-bit, like 2001:0db8:85a3:0000:0000:8a2e:0370:7334). AAAA records are used for the newer IPv6 protocol.

What is a CNAME record?

A CNAME (Canonical Name) record creates an alias from one domain name to another. It's commonly used to point subdomains like www.example.com to the main domain example.com.

What is an MX record?

An MX (Mail Exchange) record specifies the mail servers responsible for receiving email for a domain. MX records include a priority value, with lower numbers indicating higher priority.

What is TTL in DNS?

TTL (Time To Live) is the duration in seconds that a DNS record can be cached by resolvers before they need to query the authoritative DNS server again. Lower TTL values mean more frequent updates but more DNS queries.

What does DNSSEC Verified mean?

DNSSEC (DNS Security Extensions) adds cryptographic signatures to DNS records to verify their authenticity. When you see 'DNSSEC Verified', it means the DNS response has been validated and hasn't been tampered with.
