AAAA Records (IPv6 Address Records)

IPv6 address records for modern internet addressing.

CNAME Records (Canonical Name Records)

SOA Records (Start of Authority Records)

Administrative information about the DNS zone.

SRV Records (Service Location Records)

Records that specify service locations (used for SIP, XMPP, etc.).

PTR Records (Pointer Records)

Use Cases

• Network Administration: Verify DNS configuration and propagation
• Email Troubleshooting: Check MX records for mail delivery issues
• Security Analysis: Examine SPF and DKIM records
• Domain Management: Validate DNS settings and record types
• Development: Test domain resolution during application development
• Troubleshooting: Diagnose connectivity and DNS-related issues

How It Works

Our DNS Lookup tool queries public DNS servers to retrieve authoritative DNS records for the specified domain and record type. The tool provides:

• Complete record information including values and TTL
• Easy copying of individual records or all data
• JSON export for programmatic analysis
• Clear error messages for failed lookups
• Support for all standard DNS record types

Technical Notes

• DNS lookups are performed server-side for security and reliability
• Results may vary based on geographic location and DNS server selection
• TTL (Time To Live) values indicate cache duration
• Some record types may return multiple entries
• Internationalized domain names (IDN) are supported

Note: DNS propagation can take up to 72 hours globally. Records shown here represent the current state from our DNS servers.
