DNSWatch – DNS Traffic Sniffer and Analyzer

DNSWatch is a Python-based tool that allows you to sniff and analyze DNS (Domain Name System) traffic on your network. It listens to DNS requests and responses and provides insights into the DNS activity. 

Features

• Sniff and analyze DNS requests and responses.
• Display DNS requests with their corresponding source and destination IP addresses.
• Optional verbose mode for detailed packet inspection.
• Save the results to a specified output file.
• Filter DNS traffic by specifying a target IP address.
• Save DNS requests in a database for further analysis(optional)
• Analyze DNS types (optional).
• Support for DNS over HTTPS (DoH) (optional).

Requirements

• Python 3.7+
• scapy 2.4.5 or higher
• colorama 0.4.4 or higher

Installation

1. Clone this repository:

git clone https://github.com/HalilDeniz/DNSWatch.git

2. Install the required dependencies:

pip install -r requirements.txt

Usage

python dnswatch.py -i <interface> [-v] [-o <output_file>] [-k <target_ip>] [--analyze-dns-types] [--doh]

• -i, --interface: Specify the network interface (e.g., eth0).
• -v, --verbose: Use this flag for more verbose output.
• -o, --output: Specify the filename to save results.
• -t, --target-ip: Specify a specific target IP address to monitor.
• -adt, --analyze-dns-types: Analyze DNS types.
• --doh: Use DNS over HTTPS (DoH) for resolving DNS requests.
• -fd, --target-domains: Filter DNS requests by specified domains.
• -d, --database: Enable database storage for DNS requests.

Press Ctrl+C to stop the sniffing process.

Examples

• Sniff DNS traffic on interface “eth0”:

python dnswatch.py -i eth0

• Sniff DNS traffic on interface “eth0” and save the results to a file:

python dnswatch.py -i eth0 -o dns_results.txt

• Sniff DNS traffic on interface “eth0” and filter requests/responses involving a specific target IP:

python dnswatch.py -i eth0 -k 192.168.1.100

• Sniff DNS traffic on interface “eth0” and enable DNS type analysis:

python dnswatch.py -i eth0 --analyze-dns-types

• Sniff DNS traffic on interface “eth0” using DNS over HTTPS (DoH):

python dnswatch.py -i eth0 --doh

• Sniff DNS traffic on interface “wlan0” and Enable database storage

python3 dnswatch.py -i wlan0 --database
