DNS Lookup

Lookup DNS Records

Enter a domain name to check its DNS records including A, MX, CNAME, NS, TXT, and more.

Works with subdomains and full URLs as well.

Note

Results are fetched in real time from public DNS resolvers (Google and Cloudflare). Cached records may differ from authoritative responses.

What Is a DNS Lookup Tool?

A DNS lookup tool queries the Domain Name System (DNS) to retrieve the records associated with a specific domain name. Every time you visit a website, your browser performs a DNS lookup behind the scenes to translate the domain name into an IP address your computer can connect to. Our free online DNS lookup tool lets you see exactly what those records contain, giving you full visibility into a domain's configuration.

The DNS Record Checker is a comprehensive tool that allows you to check various kinds of DNS records such as the A records, MX records, CNAME records, NS records, TXT records, and many more. No matter whether you are a developer fixing issues with your domain name, an IT specialist testing email delivery options, or a website manager reviewing DNS records after migration, you will get quick and reliable results from this tool.

In contrast to the command line utilities such as nslookup and dig, our online DNS lookup runs in your web browser without any installation needed. You only need to type the domain name, select the type of record (or ALL to perform a full scan), and you'll receive your results in just seconds. Our tool will parse the URL for you automatically.

How to Check DNS Records

Follow these simple steps to look up DNS records for any domain in seconds.

1

Enter a domain name (e.g., example.com) or paste a full URL into the input field.

2

Select the DNS record type you want to check, or leave it set to ALL for a complete scan.

3

Click the 'Lookup DNS' button to query the public DNS resolvers.

4

Review the results table showing each record's type, name, value, and TTL.

"Our tool automatically extracts the hostname from full URLs and supports all major DNS record types including A, AAAA, MX, CNAME, NS, TXT, SOA, and CAA."

Why Use a DNS Lookup Tool?

A DNS lookup tool is essential for anyone who manages domains, troubleshoots websites, or works with email delivery systems.

Troubleshoot Website Issues

Use a DNS lookup tool to verify A and CNAME records for your domain. Quickly identify whether your domain points to the correct server and fix resolution problems before they affect your visitors.

Fix Email Delivery Problems

Use a DNS lookup website to check if you have correctly configured your MX records because misconfiguration of the MX records is one of the most frequent reasons for failed delivery of emails.

Verify DNS Changes

When you have updated the configuration of your DNS, check it using a DNS record checker to make sure your changes have taken place. We use public resolvers to ensure you see what everyone else on the internet sees.

Audit Domain Security

You can verify your SPF, DKIM, and DMARC settings by checking your TXT records. A DNS lookup helps you confirm that your email authentication setup protects your domain from spoofing and phishing attacks.

Research Any Domain

Search for the name servers, IP address and mail servers of any website you want to investigate. Through the DNS records lookup, you will be able to clearly understand how the website is configured behind the scenes.

Validate SSL Configuration

Verify which certificate authorities are permitted to issue SSL certificates for your domain by checking the CAA records. This DNS lookup feature helps you maintain a strong security posture and prevent unauthorized certificate issuance.

Common questions about DNS lookup and DNS records.

DNS Lookup FAQ

A DNS lookup refers to the method through which the Domain Name System is queried for the corresponding records for the domain name. In the case of DNS lookup tools, these tools will contact DNS servers to provide information in the form of A (address), MX (mail exchange), NS (name server) records, and others.
To perform a lookup of DNS records on a particular domain name, enter the domain name (example.com) into our free DNS Lookup service and choose the desired type of record to be displayed. You can choose ALL in order to display all types of records at once, or choose a particular type such as A, MX or TXT.
Some common DNS records include A records that map domains to IPv4 addresses, AAAA records that map to IPv6 addresses, MX records that route emails to email servers, CNAME records that allow domain aliases, NS records that specify the authoritative nameservers, and TXT records that hold text information like SPF and DKIM.
An A record (Address record) maps a domain name directly to an IPv4 address. When someone types your domain into a browser, the A record tells the browser which server IP to connect to. You can check A records for any domain using a DNS lookup tool to verify that your domain points to the correct hosting server.
To find MX records for your domain, enter your domain name in our DNS lookup tool and select MX as the record type. The results will show your mail exchange servers along with their priority values. Lower priority numbers indicate preferred mail servers that handle your email delivery first.
Nslookup and dig are both DNS query utilities. The latter outputs more info and is favored by system administrators when troubleshooting. Our DNS lookup utility will provide the same data as those commands without terminal access.
It takes some time for the DNS changes to be reflected everywhere as DNS servers keep records of a certain domain for as long as the TTL (Time to Live) specifies. DNS propagation can last anywhere from a few minutes to 48 hours. Use our DNS lookup tool to see if your changes were propagated through public DNS resolvers such as Google's and Cloudflare's.
TXT records hold text information related to your domain name. These records are useful for email authentication (SPF, DKIM, DMARC), domain ownership verification in services like Google Search Console, security policies, etc. You may use TXT record checker for verification.
Yes, choose NS as the type of record in our DNS lookup tool to verify nameservers used for any domain. The nameservers records help find out which DNS provider is responsible for managing the DNS records of a domain. Checking nameservers is usually the first step in domain resolution troubleshooting process.
Reverse DNS lookup translates IP addresses to domain names, which is essentially the reverse process of DNS lookup. Using the PTR records, it finds out the hostname of an IP address. Reverse DNS is used mainly for email server validation and troubleshooting networks.
