DNS Lookup
Free online DNS lookup tool, A/MX/CNAME records supported
What is DNS?
DNS (Domain Name System) translates domain names (like example.com) into IP addresses (like 93.184.216.34). DNS records contain various types of information about a domain: A records map to IPv4 addresses, AAAA to IPv6, MX to mail servers, CNAME to aliases, TXT to text data, and NS to name servers.
How to Look Up DNS Records
Enter a domain name and select the record type you want to query. The tool sends a DNS query via a public DNS resolver and displays the results. You can query specific record types or all records to get a complete picture of a domain's DNS configuration.
▶What is the difference between A and CNAME records?
An A record maps a domain directly to an IP address. A CNAME record maps a domain to another domain name, which then resolves to an IP. Use CNAME when pointing to services that may change their IP.
▶What is a TXT record used for?
TXT records store arbitrary text data. They are commonly used for SPF (email sender validation), DKIM (email signing), domain verification, and Google Site Verification.
▶Why might DNS lookup fail?
Common reasons include: the domain does not exist, the domain has no records of the requested type, DNS propagation has not completed after recent changes, or network issues preventing the query.
