domainext

Description

The domainext.py script is designed to extract the main domain from a list of subdomains. It handles different scenarios based on the length of the TLDs and the presence of ccTLDs. The script intelligently differentiates between longer TLDs (more than 4 characters) and combinations of TLDs and ccTLDs that total up to 5 characters, applying specific logic to ensure accurate domain extraction.

Features

Extracts main domains from a provided list of subdomains. Supports special handling for TLDs longer than 4 characters and ccTLD combinations up to 5 characters. Reads subdomains from a text file, processing each line as a separate entry. Prerequisites Ensure you have Python installed on your system. This script was developed with Python 3.x in mind.

Usage

a) Prepare a text file containing your subdomains, one per line. For example, subdomains.txt.

b) Run the script from the command line or terminal, passing the path to your subdomains file as an argument:

c) python domainext.py -file list.txt
