As we navigate the decentralized and highly distributed web of 2026, the Domain Name System (DNS) remains the internet's most critical "phonebook." Our utility allows you to query the most common record types — A, AAAA, MX, TXT, and CNAME — providing instant visibility into how the global network sees your domain.
How to Use the Dns Lookup
Enter the domain name (e.g., example.com) into the Domain field.
Select the DNS record type to query: A, AAAA, CNAME, MX, TXT, or NS.
Click Lookup DNS Records to query Google Public DNS.
Review the results in the output table, including name, TTL, and value.
Instant Results
Zero server lag. All lookups are processed at high speed for immediate feedback.
100% Private
Your queries are never logged or stored. Your infrastructure details remain confidential.
Common DNS Record Types & Their Uses
A Record (Address): Maps a domain name to an IPv4 address. Essential for pointing your domain to your web server.
AAAA Record (IPv6 Address): Similar to the A record, but for the modern IPv6 protocol. In 2026, having an AAAA record is increasingly important for global accessibility and performance.
CNAME Record (Canonical Name): Used to alias one domain or subdomain to another. Commonly used to point www.example.com to the root example.com.
MX Record (Mail Exchange): Specifies the mail servers responsible for receiving email on behalf of your domain. Essential for setting up services like Google Workspace or Microsoft 365.
TXT Record (Text): A versatile record used for domain verification and security. In 2026, TXT records are primarily used for SPF, DKIM, and DMARC to prevent email spoofing and phishing.
NS Record (Name Server): Indicates which DNS servers are authoritative for your domain. These are typically provided by your domain registrar or DNS hosting provider.
Expert Tips for DNS Troubleshooting
Check Your TTL (Time to Live): If you've just updated your records and don't see the changes, check the TTL. A high TTL (e.g., 86400 seconds) means changes can take 24 hours to propagate.
Use "Local-First" Diagnostics: Our tool provides a client-side view of your DNS records. If our tool shows the correct record but you still can't access your site, the issue might be your local ISP's DNS cache.
Verify Your SPF/DMARC Records: Email deliverability in 2026 depends heavily on these TXT records. Use our tool to ensure there are no syntax errors in your security strings.
Mind the Trailing Dot: In some DNS management interfaces, a trailing dot (e.g., example.com.) is required for CNAME and MX records. Forgetting this can lead to "subdomain-in-subdomain" errors.
Monitor for DNS Hijacking: Regularly check your A and NS records to ensure they haven't been changed without your knowledge, a common tactic for malicious actors.
Frequently Asked Questions
Which DNS server is used?
This tool uses Google Public DNS (dns.google) over HTTPS for secure, fast lookups.
Are the results cached?
Results are retrieved in near real-time from Google's authoritative DNS resolvers.
Are there any rate limits?
Google Public DNS allows approximately 100 requests per minute per IP address.
Can I query IPv6 addresses?
Yes. Select the AAAA record type to retrieve IPv6 addresses for a domain.
Is this tool free to use?
Yes. DNS lookups via Google Public DNS are completely free with no usage limits.
Why am I seeing old records?
If you recently changed your DNS, your local ISP or browser may have cached the old records. Try clearing your browser cache or checking the TTL of your records.
