Description

This Python tool compares the HTTP response of the given subdomain to HTTP responses of a list of IPs addresses. This list is based on:

  • subdomains supplied by the user
  • subdomains found on external sources
  • IPs found external sources

Then, a score of similarity is calculated for each response using the Levenshtein algorithm.
