What is a DNS lookup?

A DNS lookup queries the Domain Name System to retrieve records associated with a domain name, such as IP addresses (A/AAAA records), mail servers (MX records), name servers (NS records), and other record types.

What DNS record types can I query?

This tool supports A, AAAA, MX, TXT, NS, CNAME, SOA, and PTR record types. You can query them individually or look up all record types at once.

What is the TTL value in DNS records?

TTL (Time To Live) is the number of seconds a DNS record is cached by resolvers. A lower TTL means changes propagate faster, while a higher TTL reduces DNS query load.

DNS Lookup

Query DNS records for any domain. Supports A, AAAA, MX, TXT, NS, CNAME, SOA and PTR record types. Powered by Google Public DNS.

Common Record Types

A maps a domain to an IPv4 address. AAAA maps to IPv6. MX points to mail servers. NS specifies authoritative name servers.

What is TTL?

TTL (Time To Live) indicates how long a DNS record is cached by resolvers in seconds. Lower TTLs mean faster propagation of changes. Typical values range from 300 (5 min) to 86400 (24 hours).

TXT & SPF Records

TXT records store text data often used for domain verification, SPF (email authentication), DKIM, and DMARC policies. They are critical for email deliverability and security.

How to Use DNS Record Lookup

The DNS Record Lookup tool queries authoritative nameservers to retrieve DNS records for any domain. Inspect A, AAAA, MX, TXT, CNAME, NS, SOA, and other record types to troubleshoot email delivery, verify domain configuration, or audit DNS security settings. Results are displayed in an easy-to-read format.

Open the DNS Lookup Tool

Navigate to the DNS Record Lookup from the cybersecurity tools menu. The interface provides a domain input field and record type selector.

Enter the Domain Name

Type the domain name you want to query, such as example.com. Do not include the protocol (http/https) as the tool works with domain names only.

Select Record Type

Choose the DNS record type to query: A for IPv4 addresses, AAAA for IPv6, MX for mail servers, TXT for verification records, CNAME for aliases, NS for nameservers, or query all types at once.

Execute the Query

Click the lookup button to perform the DNS query. Results typically return within seconds, showing all matching records with their values and TTL information.

Analyze the Results

Review the returned records, including their values, TTL (time-to-live), and any associated priority numbers for MX records. Use this information for troubleshooting or verification.

Common Use Cases

Troubleshooting Email Delivery

Query MX, SPF, DKIM, and DMARC records to diagnose why emails are being rejected, marked as spam, or failing authentication checks.

Verifying Domain Configuration

Confirm that A records, CNAME records, and other DNS entries point to the correct servers after migrating hosting providers.

Security Auditing

Review TXT records for proper SPF and DMARC policies, and check for any unexpected or unauthorized DNS entries that could indicate compromise.

Monitoring DNS Propagation

Check whether recent DNS changes have taken effect by querying records and comparing current values against expected configurations.

Pro Tips

-Check TXT records to verify SPF, DKIM, and DMARC configurations that are critical for email deliverability and anti-spoofing protection.
-If DNS changes seem slow to propagate, check the TTL value on the old records; high TTL values mean caches hold stale data longer.
-Query NS records to confirm your domain is pointed to the correct nameservers after a hosting or registrar migration.
-Use A and AAAA lookups together to verify that both IPv4 and IPv6 addresses are properly configured for dual-stack domains.
