Extracting Domains

This tool is designed to extract domains from links and email addresses found in text files.

Settings

  • Top Level Domains. For correct operation, you must provide an up-to-date list of top-level domains, which can be downloaded from the IANA website: tlds-alpha-by-domain.txt.
  • Extract Email Domains Only. This setting allows extracting only domains that follow the @ symbol.
  • Suppress WWW — removes the www prefix from domain names. For example, if the file contains the link https://www.optinsoft.net/, enabling this option will extract optinsoft.net instead of www.optinsoft.net.
  • Output Sub Domains to Separate Files. You must provide a Domain Suffix List. An example of such a list is the PUBLIC SUFFIX LIST (more information is available in the wiki).

Output File

  • Output File — a text file containing extracted domains.

Output File Sorting

You can enable output file sorting (Sort) and duplicate removal (Remove Duplicates).
