Calculation Methodology & Formula
Queries root and authoritative nameservers in real-time using native Node.js DNS resolvers with SSRF protection against RFC 1918 and loopback networks.
DNS Query: domain.tld -> [A, AAAA, MX, TXT, NS, CNAME, SOA] + TTLWorked Example: Inspect Google.com Mail & IP Configuration
Check IPv4 address and mail server priorities for google.com.
domain:google.com
record Type:ALL
Expected OutputA: 142.250.x.x, MX: smtp.google.com (Priority 10), TXT: v=spf1...
Returns real authoritative DNS records directly from global DNS resolvers.
Technical Constraints & Limitations
- Private IP networks (127.0.0.1, 10.0.0.0/8, 192.168.0.0/16, etc.) and internal hostnames (.local, .internal) are restricted by SSRF protection.
- DNS propagation across global resolvers may take up to 24-48 hours depending on configured TTL.
Frequently Asked Questions
What is a DNS Record?
A Domain Name System (DNS) record is an address instruction stored on authoritative DNS servers that translates human-readable domain names into machine-readable IP addresses and routing directives.
What do the different DNS record types mean?
A maps domains to IPv4 addresses; AAAA maps to IPv6; MX defines mail exchange servers and priority; TXT stores domain verification and email security records (SPF, DKIM, DMARC); NS specifies nameservers; CNAME creates aliases; and SOA identifies the primary authoritative zone administrator.
Are my DNS queries stored or logged?
No. Queries are resolved dynamically to inspect live DNS records and are never logged, tracked, or associated with user identities.
