How to Use This DNS Lookup Tool

This DNS lookup tool helps you query various DNS record types for any domain name or IP address. Follow these simple steps to get started:

Step 1: Enter Domain or IP Address

In the "Domain/Hostname/IP Address" field, enter:

• A domain name (e.g., example.com)
• A hostname (e.g., www.example.com)
• An IP address for PTR/reverse DNS lookups (e.g., 8.8.8.8)

Step 2: Select Query Type

Choose the DNS record type you want to query from the dropdown menu:

• A: IPv4 address records
• AAAA: IPv6 address records
• NS: Name server records
• MX: Mail exchange records
• TXT: Text records (including DKIM, DMARC, etc.)
• SPF: Sender Policy Framework records
• CNAME: Canonical name (alias) records
• SOA: Start of Authority records
• PTR: Pointer records (reverse DNS lookups)
• SRV: Service records
• CAA: Certificate Authority Authorization records
• ANY: All available record types

Step 3: Choose DNS Provider

Select your preferred DNS provider from the dropdown:

• Google DNS (8.8.8.8): Google's public DNS service
• Cloudflare DNS (1.1.1.1): Cloudflare's public DNS service

Step 4: Perform Lookup

Click the "Lookup" button to perform the DNS query. The tool will use DNS-over-HTTPS (DoH) for secure and private queries.

Understanding the Results

After the query completes, you'll see the DNS records organized by type. Each record shows:

• Record Value: The actual DNS record data
• TTL (Time To Live): How long the record should be cached
• Record Type: The type of DNS record

Common Use Cases

• Troubleshooting email issues: Check MX records to verify mail server configuration
• Website migration: Verify A/AAAA records before changing hosting providers
• Security verification: Check SPF, DMARC, and DKIM records for email security
• Network diagnostics: Use PTR records to verify reverse DNS configuration
• SSL certificate verification: Check CAA records to see which certificate authorities are authorized
