How to use it
- Paste text, markup, or a domain list into the text area.
- Select Extract and Process Domains.
- Check the unique-domain count.
- Review each identified host, derived extension, and syntax badge.
- Copy the output table if you need the extracted inventory.
The code does not use a URL parser, so it scans any matching substring rather than validating complete URLs.
What is the purpose of the tool
This tool helps analysts reduce pasted URL text to a deduplicated list of domain-like hosts.
Protocols and paths are excluded naturally because the regular expression captures only the matching host substring.
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.
FAQs related to that specific tool
Does it parse URLs with the browser URL API?
No. A regular expression searches the raw text.
Are schemes and paths included in output?
No. Only the matching domain-like substring is listed.
Are repeated hosts removed?
Yes. Matching strings are lowercased and deduplicated.
Will text that is not a URL still match?
Yes. Any substring fitting the domain pattern can be returned.
Are ports shown?
No. Port numbers are outside the extracted host pattern.
Does the tool test whether the URLs work?
No. It makes no HTTP request.
