Frequently Asked Questions
How are multi-level TLDs handled?
We recognize public suffix list entries like .co.uk, .com.au, so "api.example.co.uk" correctly shows "api" as subdomain.
What if there's no subdomain?
URLs like "example.com" show an empty subdomain field. The domain is "example" and TLD is "com".
Does this validate if domains exist?
No, this only parses the URL structure. It doesn't check DNS or domain availability.
