HOW TO USE

How to Use DNS Lookup Tool

  1. Enter a valid domain name, such as example.com.
  2. Select the DNS record type you want to query.
  3. Click Lookup DNS.
  4. Wait for the response from the DNS resolver.
  5. Review the record name, type, value and other available information.

Tip: Try different record types when troubleshooting a domain because A, MX, CNAME, NS and TXT records serve different purposes.

DNS Lookup Tool

A DNS Lookup Tool lets you check the Domain Name System records associated with a website or domain. DNS records help browsers and other internet services determine where a domain should connect and which services are configured for it.

With this free DNS Lookup Tool, you can enter a domain name and check commonly used DNS records such as A, AAAA, MX, CNAME, NS and TXT. The results are retrieved through a public DNS-over-HTTPS service and displayed in an easy-to-read format.

What Is DNS?

DNS stands for Domain Name System. It translates human-readable domain names into information that computers and network services can use. Instead of remembering an IP address, users can enter a domain such as example.com and DNS helps determine the appropriate destination.

What Can You Check With a DNS Lookup?

  • A Record: Maps a domain to an IPv4 address.
  • AAAA Record: Maps a domain to an IPv6 address.
  • MX Record: Identifies mail servers responsible for receiving email.
  • CNAME Record: Points one domain name to another hostname.
  • NS Record: Shows the authoritative name servers for a domain.
  • TXT Record: Stores text-based DNS information commonly used for verification and email-related configurations.
  • SOA Record: Contains administrative information about a DNS zone.

How to Use the DNS Lookup Tool

  1. Enter a domain name in the lookup box.
  2. Select the DNS record type you want to check.
  3. Click the Lookup DNS button.
  4. Wait for the DNS response.
  5. Review the returned records and values.

Why Use a DNS Lookup Tool?

DNS lookup is useful when troubleshooting websites, checking domain configuration, investigating email delivery settings or verifying whether DNS changes have propagated to a public resolver.

DNS Records and Website Troubleshooting

If a website is not opening correctly, checking its DNS records can help identify configuration issues. An incorrect A or AAAA record can direct visitors to an unexpected server, while an incorrect CNAME can cause hostname resolution problems.

DNS Records for Email

MX records are especially important for email delivery because they identify the mail servers responsible for receiving messages for a domain. TXT records can also contain information used by email authentication systems and domain verification services.

Is DNS Lookup Safe?

A DNS lookup only requests publicly available DNS information for the domain being queried. This tool does not require you to upload files or provide account passwords.

DNS Lookup vs IP Lookup

A DNS lookup focuses on DNS records associated with a domain, while an IP lookup generally provides information associated with an IP address. Both can be useful when troubleshooting internet and website configuration issues.
