DNS Lookup - Complete Domain Analysis Tool

DNS Lookup is a powerful domain analysis tool that provides comprehensive DNS record lookups, email security assessments, and website performance insights. Perfect for domain administrators, security professionals, and developers who need detailed DNS information and email security analysis.

What is DNS Lookup?

DNS Lookup is an advanced domain analysis actor that goes beyond basic DNS queries. It performs deep DNS analysis, email security auditing, SSL certificate inspection, and global propagation testing - all in one comprehensive tool.

Supported DNS Record Types

Record Type	Description	Purpose
A	IPv4 Address	Maps domain to IPv4 address
AAAA	IPv6 Address	Maps domain to IPv6 address
MX	Mail Exchange	Email server routing
TXT	Text Records	SPF, DKIM, DMARC, verification
NS	Name Server	Authoritative DNS servers
CNAME	Canonical Name	Domain aliases and redirects
SOA	Start of Authority	Zone configuration and settings
SRV	Service Records	Service location and ports
PTR	Pointer Records	Reverse DNS lookups
CAA	Certificate Authority	SSL certificate authorization

All record types are queried simultaneously for comprehensive domain analysis.

How to Use DNS Lookup

Simple Input Format

{
  "domains": ["example.com", "github.com", "https://www.google.com"]
}

Domain Limit: Maximum 100 domains per run. For larger lists, split into multiple batches and run separately.

Flexible Domain Input

The tool accepts domains in any format:

• example.com - Basic domain
• www.example.com - With subdomain
• https://example.com - With protocol
• http://www.example.com/path - Full URLs

All formats are automatically normalized for consistent analysis.

Advanced Configuration Options

{
  "domains": ["example.com"],
  "checkPropagation": true,
  "enableSslInspection": true,
  "performReverseLookup": true,
  "enableEnrichment": true,
  "checkPerformance": true,
  "checkSecurityHeaders": true,
  "enableDnssec": true
}

Email Security Scoring System

Our transparent email security scoring (0-100 points):

• 25 points: Valid SPF record with proper policy
• 25 points: DMARC policy set to reject or quarantine
• 25 points: DKIM records discovered
• 15 points: Multiple MX servers for redundancy
• 10 points: Optimal TTL configuration

Unlike proprietary scoring systems, our methodology is completely transparent and published.
