How It Works
Check DNS Records in Three Simple Steps
Enter a domain, choose the DNS record type and review the information returned by the domain name system.
Select record type
Choose A, AAAA, MX, NS, TXT, CNAME, SOA or CAA. Select All Records when you need a complete DNS overview for the domain.
Review the report
Examine record values, hostnames, priorities and TTL information. You can also copy or download the complete DNS report.
DNS Record Guide
Understanding Common DNS Record Types
Each DNS record has a specific purpose in connecting domains with websites, email services and verification systems.
A Record
An A record points a domain or hostname to an IPv4 address, such as 192.0.2.1. It is commonly used to connect a domain with a web server.
AAAA Record
An AAAA record connects a hostname with an IPv6 address. It performs the same role as an A record but supports the newer IPv6 addressing system.
MX Record
An MX record identifies the mail servers that receive email for a domain. The priority value determines which mail server is contacted first.
NS Record
An NS record identifies the authoritative name servers responsible for managing DNS information for a domain.
TXT Record
TXT records store text-based information. They are commonly used for SPF, DKIM, DMARC, ownership verification and other security configurations.
CNAME Record
A CNAME record points one hostname to another hostname. It is often used for subdomains, content delivery networks and hosted services.
SOA Record
An SOA record contains administrative information about a DNS zone, including its primary name server, serial number and refresh settings.
Time to Live
TTL determines how long DNS resolvers may cache a record before requesting updated information from the authoritative name server.
DNS Propagation
DNS changes may not appear everywhere immediately. Cached records can remain active until their TTL expires and resolvers request the updated record.
Common Uses
Why Check a Domain’s DNS Records?
DNS lookup information can help website owners, developers and administrators diagnose configuration problems and verify domain services.
Verify website hosting
Check A and AAAA records to confirm that a domain points to the correct web server IP address.
Troubleshoot email delivery
Review MX and TXT records to investigate email routing, SPF configuration and domain verification.
Confirm name servers
Check whether the domain is using the expected authoritative name servers after a hosting or DNS provider change.
Check CDN configuration
Review CNAME records used by content delivery networks, hosted platforms and external services.
Verify ownership records
Confirm TXT records added for Google Search Console, Microsoft services, email providers and other verification platforms.
Diagnose DNS problems
Identify missing, incorrect or outdated DNS records that may prevent websites, email or subdomains from working correctly.
Frequently Asked Questions
DNS Lookup FAQs
Learn more about DNS records, caching, propagation and common domain configuration issues.
What is a DNS lookup?
A DNS lookup retrieves Domain Name System records associated with a domain or hostname. These records can include IP addresses, mail servers, name servers, aliases and verification information.
Which DNS records can this tool check?
This DNS Lookup tool can check A, AAAA, MX, NS, TXT, CNAME, SOA and CAA records. You can select one record type or run a lookup for all supported records.
Why are no DNS records appearing?
The selected record type may not exist for the hostname. The domain may also be invalid, expired, recently updated or affected by a temporary DNS resolver problem.
How long do DNS changes take to update?
DNS changes can begin appearing within minutes, but cached records may remain active until their TTL expires. Global propagation time depends on the previous TTL and resolver caching.
What does TTL mean in DNS?
TTL means Time to Live. It tells DNS resolvers how many seconds they may cache a record before checking for an updated version.
Can I check a subdomain?
Yes. You can enter a subdomain such as blog.example.com or mail.example.com to retrieve DNS records associated with that hostname.
Can this tool check private or local DNS records?
No. This tool checks publicly available DNS records resolved by the web server. Private network records, local hosts files and internal DNS zones are not normally accessible.
Is the DNS report saved?
The report is generated when you submit the lookup form. You may copy or download the result for your own records.
