DNS Lookup
Query DNS records for any domain using Google's public DNS API. See A, AAAA, MX, CNAME, TXT, and NS records.
About DNS Lookup
Our free DNS Lookup tool queries Google's public DNS-over-HTTPS API to retrieve DNS records for any domain. See A records (IPv4 addresses), AAAA records (IPv6 addresses), MX records (mail servers), CNAME records (aliases), TXT records (text data), and NS records (name servers).
DNS (Domain Name System) is the internet's phone book — it translates domain names like example.com into IP addresses that computers use to connect. Understanding DNS records is essential for website management, email configuration, troubleshooting connectivity issues, and verifying domain settings.
The tool uses Google's public DNS API at dns.google, which provides reliable, fast DNS resolution. All queries are made from your browser via HTTPS, ensuring your lookups are private and encrypted.
Frequently Asked Questions
Q What is an A record?
An A (Address) record maps a domain name to an IPv4 address. For example, example.com might have an A record pointing to 93.184.216.34. When you type a domain in your browser, the A record tells your computer which IP address to connect to. Most websites have at least one A record.
Q What is an MX record?
MX (Mail Exchange) records specify the mail servers responsible for receiving email for a domain. They include a priority value — lower numbers have higher priority. For example, if your domain uses Google Workspace, your MX records would point to Google's mail servers.
Q Why might a DNS lookup fail?
DNS lookups can fail if the domain doesn't exist, has no records of the requested type, or if there's a network connectivity issue. Some domains also block DNS-over-HTTPS queries. If the lookup fails, try a different record type or verify the domain name is spelled correctly.
