Network Reference brings together 5 free tools with no sign-up for technical lookups. Port references identifies the main TCP and UDP ports, HTTP status codes gives the meaning of a status, and MIME Types helps find the type linked to an extension. User-Agent analyzer details the browser, engine and platform, while URL Solver rebuilds a relative URL against a base. These aids suit developers and support teams.
Pick based on the value you need to decode. For a port number, start with Port references. For a status returned by a page, use HTTP status codes. An unknown file extension is checked with MIME Types. If you are analyzing a request, User-Agent analyzer identifies the client, and URL Solver handles relative addresses. These tools often act as quick reminders during integration or troubleshooting.
