DNS Enumerator

Overview

This project is a Python script designed to enumerate various DNS records for a given domain or a list of domains. It supports querying multiple types of DNS records, including A, AAAA, NS, CNAME, MX, PTR, SOA, and TXT records.

Features

• Query individual domains for DNS records.
• Batch query multiple domains from a file.
• Supports a wide range of DNS record types.
• Handles errors gracefully and provides informative output.

Prerequisites

• Python 3.x
• dnspython library You can install the required dnspython library using pip:

pip install dnspython

Usage

Command-Line Arguments

The script accepts the following command-line arguments:

• -d, --domain-name: Specify a single domain name to look up.
• -f, --file: Provide a file containing a list of domain names to look up, one per line.

Example Commands

Query a Single Domain

To query a single domain for all supported DNS records:

python dns_enum.py -d example.com

Query Multiple Domains from a File

To query multiple domains listed in a file:

1. Create a text file (e.g., domains.txt) with each domain name on a new line.
2. Run the script with the -f option:

python dns_enum.py -f domains.txt

Example Output

For a domain with various DNS records, the output will be:

A Records
    - 93.184.216.34

AAAA Records

NS Records
    - ns1.example.com.
    - ns2.example.com.

CNAME Records

MX Records
    - 10 mail.example.com.

PTR Records

SOA Records
    - ns1.example.com. hostmaster.example.com. 2021040401 7200 3600 1209600 3600

TXT Records
    - "v=spf1 include:_spf.example.com ~all"

If a domain does not exist, the script will output:

example.com does not exist.

Script Details

The script dns_enum.py consists of the following parts:

• RECORD_TYPES: A list of DNS record types to query.
• get_args(): Parses command-line arguments.
• process_file(domain_file): Reads domains from a file and resolves each one.
• resolve_domain(domain): Resolves and prints DNS records for a given domain.
