Who owns this?
RDAP is the machine-readable successor to WHOIS. Look up the registrable domain of the host above to see who registered it and when — a brand-new look-alike is a red flag.
RDAP doesn't cover every TLD. Full record at ICANN Lookup
The extension at the end of a path is only a convention — what really decides how a browser treats a file is the Content-Type header the server sends. Clean URLs often drop the extension entirely.
Look-alikes & typosquatting
Query-string mischief
Misleading redirects
Compare two URLs
Same origin, same site, or another site entirely? The answer decides what the browser shares between them: cookies, storage, caches, and whether a script may read the response.
Resolve a relative URL
A link written ../fonts/a.woff2 means nothing alone. The browser resolves it against the address of the document (or stylesheet) it appears in.

URL parsing is native (URL / URLSearchParams); host classification uses the Public Suffix List via tldts. Styled with Vanilla Breeze.
Honest limits: the Public Suffix List is a bundled snapshot (updated with the library, not live). Some schemes shown (magnet) are de-facto conventions with no IETF RFC.
