vPort
What is on your network, and which doors are open.
The problem
Somebody asks what is on the office network and there is no good way to answer. Windows will show you a workgroup list that has been wrong since 2015; the router will show you leases with no names on them. So the answer is usually a guess, and the machine nobody remembers installing stays there.
The scanners that do answer it often answer it wrongly. Windows ping exits successfully when the router replies "nothing is at that address" — so a tool that trusts the exit code reports every empty address on the subnet as a live machine, and the list it hands you is fiction.
What it does
1Every machine, with its name
Address, network name, hardware address, who made it, how quickly it answered and which ports are open. Results appear as they are found rather than after a minute of nothing.
2It finds the quiet ones too
A Windows machine with its firewall up ignores pings but still answers the request underneath. vPort reads the ARP table after the sweep and lists those as well — marked, with what it actually knows: did not answer a ping, but it is there.
3Open, closed and no answer are three different things
A refused connection means the machine is there and said no. A timeout means a firewall swallowed it. Calling the second one "closed" tells somebody their firewall is off when it is on.
4Names that stay put
Call it "Reception PC" once. The name is attached to the hardware address, not the IP, so it follows the machine when the router hands out a different address — and does not land on somebody else's laptop.
5Shared folders
What each machine is sharing, and one click to open it in Explorer. If a machine will not say, vPort says that — which is not the same as nothing being shared.
6What changed since last time
Scans are kept, and compared by device rather than by address — so a router restart that reshuffles every lease does not report the whole office as new.
7It knows a randomised address when it sees one
Phones and laptops invent a hardware address per network now. Those have no manufacturer and never will. vPort says so instead of leaving a blank that looks like a mystery device.
8A list for whoever asked
The whole scan as a CSV that opens straight in Excel — with the encoding right, and machine names defused so a name somebody else chose cannot arrive as a formula.
Why it is worth it
Ping, ARP, a TCP connection, and asking a machine what it shares. No driver, no administrator prompt, and nothing hidden — a scan from vPort looks in the other machine's logs exactly like what it is.
No password attempts, no exploits, no "auditing". It reports what a machine volunteers. Finding out that Remote Desktop is open is an administrator's job; getting through it is not this tool's business.
A /16 is 65,534 addresses and a /8 is sixteen million. vPort puts the number in front of you rather than starting a progress bar that never moves.
No account, no cloud, no telemetry. What it finds stays on the machine it found it from.
How you use it
The network this machine is on is already filled in.
Machines appear as they are found. Stop works immediately, and what has been found so far stays.
Its ports, its shares, and a box to give it a name you will recognise next time.
And vPort will tell you what appeared and what went.
What it needs
| Windows | 10 or 11, 64-bit |
|---|---|
| Installs to | Your user profile — no administrator prompt |
| Needs | Nothing else installed first |
| Network | Your own local network — nothing is sent anywhere else |
| Goes with | vSys, for what is inside one of the machines it finds |
What it will not do, said plainly
vPort is for the network you run. It does not try passwords, does not attempt to get into anything, and does not hide what it is doing. If you point it at somebody else's network you are doing something we did not build it for.
The manufacturer list is a curated one, not the whole IEEE registry — a few hundred prefixes covering the equipment actually found on an office network. Anything else is left blank, which means "not in the list", never "unknown device". Bundling a stale copy of the whole registry and presenting the answers as fact would be worse.
A machine that answers nothing at all — no ping, no ARP entry, no open port — cannot be found by any tool that works this way, and vPort does not pretend otherwise.
