Mac network utility · for people who trace cables

Know exactly which switch port you're plugged into.

Plug in. Run one command. PortSpot reads the switch's own LLDP/CDP and your DHCP lease and tells you the switch, port, VLAN, and subnet — in one window.

  • Switch, Port ID & VLAN straight from LLDP/CDP — no config on the switch.
  • Full IP picture — DHCP server, lease timers, gateway, DNS, subnet range, egress IP.
  • Catch trouble — rogue DHCP servers and duplicate-IP conflicts on the segment.

No spam — one email when the beta opens.

The wedge

A port-ID probe that lives on your laptop.

Field techs carry a dedicated hardware tester just to answer "which port is this?" PortSpot does the same read over software — on the Mac that's already in your bag.

What it reads

Everything about where you're standing.

Switch, port & VLAN

Listens for the switch's LLDP/CDP advertisement and names the exact switch, port, native + voice VLAN — nothing to configure on the switch side.

The full IP story

DHCP server and lease timers (T1/T2), gateway with latency, DNS + search domain, subnet range, and the public egress IP the internet sees.

Trouble on the wire

An opt-in active scan flags rogue DHCP servers handing out leases and duplicate-IP conflicts before they take a user offline.

How it works

Three seconds, plugged to answer.

01

Plug in

Drop your Ethernet (or USB adapter) into any switch port. PortSpot follows whatever's live — it doesn't care what the interface is named.

02

Open PortSpot

It reads the switch's LLDP/CDP frame and your DHCP lease in the background — no switch access, no login, no setup.

03

Read the panel

Switch, port, VLAN, subnet, DHCP, DNS, gateway — one window. Copy it into a ticket or export it.
