DNSenum

DNSenum is a powerful open-source tool used for DNS enumeration and information gathering.

Purpose: DNSenum is designed to discover and extract valuable information related to DNS records, subdomains, and zone transfers.

Key Features:

• Subdomain Enumeration

• Zone Transfer Analysis

• Network Range Scanning

• WHOIS Information Retrieval

• Enumeration using Dictionary Files

Examples:

1. Subdomain Enumeration:

   dnsenum example.com

   Initiates a basic subdomain enumeration on the target domain "example.com," identifying additional subdomains.

2. Zone Transfer Analysis:

   dnsenum --enum -f /path/to/targets.txt

   Conducts zone transfer analysis on a list of target domains specified in the file, revealing authoritative name servers.

3. Network Range Scanning:

   dnsenum --enum -r 192.168.1.0/24

   Performs DNS enumeration on a specific network range (CIDR notation) to identify active hosts and associated DNS records.

4. WHOIS Information Retrieval:

   dnsenum --enum -w -f /path/to/targets.txt

   Fetches WHOIS information for the domains listed in the specified file, providing details about domain registration.

5. Enumeration using Dictionary Files:

   dnsenum --enum -f /path/to/targets.txt -w /path/to/wordlist.txt

   Utilizes a dictionary attack approach, attempting to enumerate subdomains using a specified wordlist.

Use DNSenum responsibly and adhere to ethical hacking guidelines and legal constraints when conducting security assessments.
