What is the Dns Checker?

The DNS Lookup Tool queries the Domain Name System to retrieve all public DNS records associated with a domain name. DNS is the internet's address book it translates human-readable domain names like example.com into the IP addresses, mail servers, and other configuration data that computers need to communicate. Every website, email service, and internet-connected application relies on DNS records being correct. This tool performs a comprehensive lookup across all major record types: A (IPv4 address), AAAA (IPv6 address), MX (mail servers), NS (nameservers), TXT (SPF, DKIM, verification tokens), CNAME (aliases), and SOA (zone authority).

How to use the Dns Checker

Enter a domain name in the input field for example, google.com or yourwebsite.com and click Lookup DNS. You do not need to include http:// or www; the bare domain name works best. Results appear in a table showing the record type, host name, value, and TTL (time-to-live in seconds). Use the record type badge column to filter visually. Blue badges are A records (IPv4), purple are NS records, green are MX records, and orange are TXT records. The Value column shows the most relevant data for each type IP addresses for A/AAAA records, hostnames for MX and CNAME, and raw text for TXT records including SPF and DKIM entries.

Frequently asked questions

A DNS lookup queries the Domain Name System to find records associated with a domain. These records tell browsers, mail servers, and other services how to reach the domain which IP address to connect to, which server handles email, and more. This tool performs a live lookup directly against DNS resolvers.
A records map domains to IPv4 addresses. AAAA records map to IPv6. MX records define mail servers. NS records specify authoritative nameservers. TXT records hold arbitrary text (SPF, DKIM, verification tokens). CNAME records are aliases pointing to another hostname. SOA records contain zone authority information like the primary nameserver and refresh intervals.
DNS records are cached at multiple levels browser, OS, ISP resolver, and CDN. Different tools may hit different resolvers or read cached data with varying TTLs. After a DNS change, old values persist until each cache's TTL expires. Full propagation can take anywhere from minutes to 48 hours depending on the TTL set on the record.
TTL (Time To Live) is the number of seconds that DNS resolvers are allowed to cache a record before fetching a fresh copy. A low TTL (60 - 300 seconds) means changes propagate quickly but generates more DNS queries. A high TTL (86400 = 24 hours) reduces DNS traffic but means updates take longer to roll out globally. Lower your TTL before planned migrations.
Yes DNS records are publicly accessible by design. Any domain's A, MX, NS, TXT, and other records can be queried by anyone. This is how the internet works: resolvers worldwide need to look up this data to route traffic correctly. Private or internal DNS records on a corporate intranet are not accessible through public lookups.
