Free DNS Checker Online
Use our free DNS Checker to look up DNS records for any domain name. Check A, AAAA, MX, CNAME, TXT, NS, SOA and other common DNS records directly from your browser.
DNS records help connect a domain name with servers and online services. A DNS lookup can be useful when checking website configuration, email settings, domain propagation and server changes.
What Can You Check With DNS Checker?
- A Record: Finds the IPv4 address associated with a domain.
- AAAA Record: Finds the IPv6 address associated with a domain.
- MX Record: Shows mail servers configured for the domain.
- CNAME Record: Shows canonical domain aliases.
- TXT Record: Displays text records commonly used for verification and email security.
- NS Record: Shows the authoritative name servers for a domain.
- SOA Record: Displays important information about the domain's DNS zone.
- CAA Record: Shows which certificate authorities are allowed to issue certificates for the domain.
- PTR Record: Can be used for reverse DNS lookups when an IP address is entered.
Why Check DNS Records?
DNS checking is useful when moving a website to a new hosting provider, changing name servers, configuring email, verifying domain ownership or troubleshooting a website that is not resolving correctly.
How DNS Works
When someone enters a domain name into a browser, DNS helps translate that human-readable domain into information that computers and network services can use. The browser can then connect to the appropriate server.
DNS changes may not appear everywhere immediately because DNS information can be cached by different resolvers. Checking records from a DNS lookup tool can help identify whether the expected records are being returned.
DNS Checker vs DNS Propagation Checker
A DNS Checker queries DNS records for a selected record type. A DNS propagation checker generally compares DNS responses from multiple DNS resolvers or locations. Both tools can be useful when troubleshooting DNS changes.
Is DNS Checker Free?
Yes. This online DNS Checker is designed to provide quick DNS lookups without requiring software installation or registration.
