Mac network utility · for people who trace cables
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.
No spam — one email when the beta opens.
The wedge
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
Listens for the switch's LLDP/CDP advertisement and names the exact switch, port, native + voice VLAN — nothing to configure on the switch side.
DHCP server and lease timers (T1/T2), gateway with latency, DNS + search domain, subnet range, and the public egress IP the internet sees.
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
Drop your Ethernet (or USB adapter) into any switch port. PortSpot follows whatever's live — it doesn't care what the interface is named.
It reads the switch's LLDP/CDP frame and your DHCP lease in the background — no switch access, no login, no setup.
Switch, port, VLAN, subnet, DHCP, DNS, gateway — one window. Copy it into a ticket or export it.
