URL & Domains

Every link and domain carries information that is hidden from a normal visitor: who owns the domain and when it expires, whether its certificate is valid, where a redirect finally lands, and what headers the server sends back.

Domain WHOIS and the SSL Checker answer the ownership and security questions. The Redirect Checker, HTTP Status Code Checker and HTTP Headers Parser are the first things to try when a page moved or behaves oddly, and the URL Unshortener shows where a short link goes before you click it.
