Usage

Run the script:

python dns_enum.py

The tool provides two main functions:

1. Generate a subdomain wordlist:

   • Creates a file containing common subdomain names
   • Customizable output file name

2. Perform DNS enumeration:

   • Resolves various DNS record types
   • Discovers subdomains using a wordlist
   • Displays results in a readable format
