How to use it
- Paste text, markup, or a domain list into the text area.
- Select Extract and Process Domains.

- Review each identified host, derived extension, and syntax badge.
- Copy the output table if you need the extracted inventory.
The code does not recognize api, dev, staging, mail, admin, or any other environment label.
What is the purpose of the tool
This page helps administrators collect unique hosts and subdomains that appear in pasted text.
The result preserves each full matching host in a flat list without categorizing or grouping environments.
What parameters it generates in output
Processed Inventory reports the number of unique domain-like strings found. # numbers each output row.
Identified Domain / Host is the lowercase matched string. TLD / Extension joins every label after the first dot. Syntax Status shows Valid RFC when every label passes the page's length and edge-character pattern, otherwise Invalid Syntax.
