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.
Subdomains remain separate matches, and the tool does not determine registrable root domains.
What is the purpose of the tool
This page lets administrators inventory unique host strings found across pasted text and view their derived extension text.
It does not merge those hosts beneath a parent domain or create root-domain groups.
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
Are subdomains consolidated under a root?
No. Each unique matched host gets its own row.
Does it know multi-label public suffixes?
No. The Public Suffix List is not used.
What appears in the extension column?
It contains every label after the first dot, which is not necessarily the public suffix.
Are hosts sorted by parent domain?
No. They retain first-match order.
Does it remove duplicates?
Yes. Case-normalized exact duplicates are removed.
Can it fetch hosts from a website?
No. The source content must be pasted.
