Key Features of the Domain Scanner

This tool utilizes multiple methods to verify domain name availability, ensuring accuracy and reliability.

• Multi-Method Checks: It goes beyond basic WHOIS lookups. The tool checks DNS records (NS, A, MX), WHOIS information, and SSL certificates.
• Advanced Filtering: Target specific patterns using regular expressions to narrow your search and find the perfect match.
• Concurrent Processing: Speed up the process by checking multiple domains simultaneously with configurable worker threads.
• Smart Error Handling: Automatic retries for failed queries ensure you don't miss potential available names due to temporary issues.

Options Explained: Tailor Your Domain Search

Customize your search with these options:

• -l int: Domain length (e.g., -l 5 for 5-character domains).
• -s string: Domain suffix (e.g., -s .com or -s .net).
• -p string: Domain pattern:
  • d: Pure numbers (e.g., 123.li).
  • D: Pure letters (e.g., abc.li).
  • a: Alphanumeric (e.g., a1b.li).
• -r string: Regular expression filter (e.g., ^[a-z]{2}[0-9]$).
• -delay int: Delay between queries (milliseconds) to avoid rate limiting.
• -workers int: Number of concurrent workers (increase for faster scanning).
• -show-registered: Show registered domains in output.

Real-World Examples to Find Your Perfect Domain

• Finding Short, Brandable Domains: go run main.go -l 2 -s .com -p D -workers 30 (Checks 2-letter .com domains).
• Targeting Numbered Domains: go run main.go -l 4 -s .net -p d (Checks 4-digit .net domains).
• Using a Regular Expression: Looking for two letters followed by two numbers .org: go run main.go -l 4 -s .org -p a -r "^[a-z]{2}[0-9]{2}$"

Understand the Output: Decoding Domain Status

The domain name availability checker provides clear status updates:

• AVAILABLE!: The domain is free for registration
• REGISTERED [DNS_NS, WHOIS]: The domain is registered, with verification signatures indicating the reasons.

Verification Signatures Explained:

• DNS_NS: Domain has name server records.
• DNS_A: Domain has IP address records.
• DNS_MX: Domain has mail server records.
• WHOIS: Domain is registered according to WHOIS information.
• SSL: Domain has a valid SSL certificate.
