My Connection Info
Shows your public IP, its network and everything this tab reveals — browser, screen, language, time zone, connection — and names what a website genuinely cannot see, starting with your MAC address.
Everything this tab actually tells a website, laid out with the source of each value: the public address the request came from, the browser and platform it announces, the screen, the language, the time zone, the connection. The second half is the point — a plainly stated list of what a site cannot find out from a visit, starting with the MAC address that dozens of pages claim to show you.
The public IP is where this request came from; the reverse name and the announcing network come from DNS alone. Everything else on this page was read inside this tab and never sent anywhere. Nothing is stored.
My public IP
The address the internet uses to reach you. Everyone behind the same router or office network shares it.
Looking up…
What this site cannot see
Things people are often told a website can work out from a visit, which it genuinely cannot.
Your MAC address (the network card’s hardware id)
No web standard exposes it. This is not a browser blocking something — the route simply does not exist. A site that claims to show it is showing you something else, or making it up.
The private IP behind your router, such as 192.168.x.x
WebRTC used to leak it. Browsers now substitute a random .local name in that position, so what leaks is meaningless.
Your city or district
An IP address tells you the country its block was registered in, and no more. Anything finer is guesswork unless you grant the location permission yourself.
Your name, phone number or subscriber details
Your carrier and the services you signed up to hold those. None of it travels with a page request.
Your other tabs, your other programs, your files
Tabs are isolated from one another, and a page can read only the files you pick for it yourself.
The network path to your machine (traceroute)
Tracing a route needs raw sockets and control over TTL, neither of which a browser gives a page.
How to use it
Open it — that is the whole input
There is nothing to type. The address is read from the request as it arrives; everything else is read from the tab after the page loads.
Read the hint under each value
Each row says where its value came from and where it misleads — the CPU core count is what the browser chooses to report, the memory figure is deliberately coarse, the connection speed is an old estimate rather than a measurement.
Read the list of absences
The last section is not a disclaimer. It is six specific claims other sites make, each with the reason it is false — and it is the part worth sending to whoever told you a website had your MAC address.
Common questions
Can a website really not see my MAC address?
It cannot. There is no web API that exposes it — not one a browser blocks, one that was never built. A MAC address does not travel past the first router in any case, so even the server would only ever see its own gateway. Any site showing you one is showing you something else.
Why does it not show my city?
Because the honest answer stops at the country the address block was registered in. City-level databases are commercial estimates, frequently wrong by hundreds of kilometres, and a page that prints one as a fact is guessing with a confident face.
Is any of this recorded?
No. The IP lookup is the same DNS-only route the IP info tool uses and stores nothing; every other value is read in your browser and never sent. Reloading gives the same answers because they are read again, not remembered.
Some rows say the value is not available
Safari and Firefox do not implement the Network Information API, and Client Hints are Chromium-only, so the connection class and the platform name are simply absent there. The row is greyed rather than filled with a guess.
Does a VPN change what is shown?
The address, its network and the registry country become the VPN provider’s. The browser half — screen, language, time zone, fonts — is untouched, and a time zone that disagrees with the address is one of the ordinary ways VPN use is spotted.
Next
These accept what this tool produces, so the result can go straight in.
DNS Lookup
Queries A, AAAA, CNAME, MX, TXT, NS, SOA, SRV, CAA and PTR records over DoH, with TTL and the DNSSEC bit shown, from Cloudflare or Google.
IP Address Info
Shows your public IP or any address with its reverse name, ASN, announcing network, prefix and registry country from Team Cymru’s DNS data — no city-level geolocation.
MAC Vendor Lookup
Identifies the hardware vendor from a MAC address OUI prefix and normalises the address format.
User-Agent Parser
Breaks a user-agent string into browser, engine, OS and device, and shows your own for comparison.
HTTP Request Builder
Composes and sends a GET/POST/PUT/PATCH/DELETE/HEAD request with custom headers and a body, and shows the status, headers, body and timing — without ever forwarding cookies or Authorization.
Currency Converter
Converts between about thirty currencies at the ECB’s daily reference rates, crossed through the euro, or at a rate you type in.
