Guide to Using DNSmap for Subdomain Enumeration

Posted on

1. Install DNSmap:

  • Download DNSmap: DNSmap is available on GitHub. Clone the repository to your local machine.
  git clone https://github.com/makefu/dnsmap.git
  • Install Dependencies: Ensure you have the required dependencies installed. DNSmap is written in Python and requires the dnspython library.

2. Prepare Target Domain:

  • Identify Target Domain: Determine the domain you want to enumerate subdomains for.

3. Run DNSmap:

  • Basic Subdomain Enumeration:
  python dnsmap.py <domain>

Replace <domain> with the target domain.

  • Advanced Options:
  • -r: Perform recursive subdomain enumeration.
  • -w <wordlist>: Specify a custom wordlist for brute-force enumeration.
  • -i <IP>: Specify custom DNS server IP address for querying.

4. Analyze Results:

  • Review Output: DNSmap will display the discovered subdomains along with their corresponding IP addresses.
  • Interpret Results: Analyze the output to identify potential subdomains, including variations and permutations, that may be associated with the target domain.

Tips and Considerations:

  • Wordlist Customization: DNSmap allows you to use custom wordlists for brute-force subdomain enumeration. Customize the wordlist to include common subdomains, variations, and permutations.
  • Recursive Enumeration: Use the -r option to perform recursive subdomain enumeration, which may uncover additional subdomains by querying discovered subdomains recursively.
  • DNS Server Customization: Specify custom DNS server IP addresses using the -i option to use alternative DNS servers for querying, which can be useful for bypassing DNS rate limiting or censorship.
  • Integration with Other Tools: Integrate DNSmap with other reconnaissance tools or scripts for comprehensive subdomain enumeration and analysis.

By following this guide, you can effectively use DNSmap for subdomain enumeration to discover potential subdomains associated with a target domain. Always use such tools responsibly and ethically, and ensure compliance with applicable laws and regulations.
