DMARC-Subdomains.py is a Python script designed to retrieve a list of domains that share the same DMARC (Domain-based Message Authentication, Reporting, and Conformance) record as a specified domain. This tool leverages the Playwright library for web automation to fetch this data from the www.dmarc.live, and Beautiful Soup for parsing the HTML content to extract the domain names.
- Fetches and prints a list of domains with the same DMARC record as the input domain.
- Uses asynchronous programming for efficient web scraping.
- Simple CLI for easy operation.
