What does whoami show?
Whoami returns the request your browser sent to the server, exactly as the server sees it. It shows your public IP address and the full set of HTTP headers. A typical request carries Host, which names the site requested, User-Agent, which identifies the browser and operating system, Accept-Language, which lists your preferred languages, and Referer, which is the page you came from. Behind a proxy or CDN you also see added headers that reveal the real client address.
Each header has a purpose and a limit. X-Forwarded-For and CF-Connecting-IP are added by proxies and list the chain of addresses before the request reached the server, so they help debug geo-routing but are easy to spoof. User-Agent tells you the client, but any script can set it arbitrarily, so never trust it for access control. Reading the raw headers is the quickest way to confirm what a CDN, load balancer or VPN forwards on your behalf.
How to read the whoami result
- Open the page: your IP and headers load automatically.
- Find your public IP in the first row.
- Scan the header list for Host, User-Agent and Accept-Language.
- Look for X-Forwarded-For or CF-Connecting-IP to see the proxy chain.
Frequently asked questions about headers
Can a header identify me personally?
Not by itself. Headers plus an IP address narrow down a connection, but they do not name a person; identifying details come from cookies, accounts or other data you supply.
Why does User-Agent look unusual?
VPNs, privacy extensions and scripts often change or strip it, so an unexpected value usually means a tool rewrote the request rather than a different device.
Is my request stored?
The page reflects your own request back to you and does not build a profile; the headers shown are the ones your browser sent on that visit.
