DNS Lookup Tool
Query A, MX, TXT, CNAME, SPF and DKIM records for any domain using Google's DNS over HTTPS. Results appear in seconds.
What is a DNS Lookup?
DNS (Domain Name System) translates domain names like encoder.guru into IP addresses. A DNS lookup queries the DNS system for the records associated with a domain: A records (IPv4 addresses), AAAA records (IPv6), MX records (mail servers), TXT records (SPF, DKIM, domain verification), CNAME records (aliases), and NS records (nameservers).
How to do a DNS lookup online
- Enter a domain name (e.g. google.com) in the input field.
- Select the record type: A, AAAA, MX, TXT, CNAME, NS, or ALL.
- Click Lookup to query the DNS system.
- The DNS records and their TTL values appear instantly.
Frequently Asked Questions
What is an A record?
An A (Address) record maps a domain name to an IPv4 address. When you type a URL in your browser, DNS resolves the domain to an A record to find the server's IP address.
What is an MX record?
An MX (Mail Exchange) record specifies the mail servers responsible for receiving email for a domain. Each MX record has a priority value — the server with the lowest number is tried first.
What is a TXT record used for?
TXT records store arbitrary text for a domain. Common uses include SPF (email authentication), DKIM public keys, DMARC policies, and domain ownership verification for Google Search Console and other services.
What is TTL in DNS?
TTL (Time to Live) is the number of seconds that DNS resolvers cache a record before re-querying the authoritative nameserver. A TTL of 300 means the record can be cached for 5 minutes. Lower TTLs are useful during DNS migrations; higher TTLs reduce DNS query load.
What is a CNAME record?
A CNAME (Canonical Name) record is a DNS alias that points one domain name to another. For example, www.example.com might CNAME to example.com. The final resolved IP comes from the target domain's A record.
