MAC address lookup: find the switch port of any device.
Where is this PC plugged in? Which port is that compromised laptop on? Type a MAC address or an IP address and ConnectMyAssets answers with the switch, the port, the VLAN, the vendor and when the device was first and last seen. IP to switch port lookups follow the ARP tables to the MAC addresses behind the IP, and uplinks are recognised from LLDP/CDP, so the answer is the access port the device is really plugged into, not the trunk that carries its traffic.

USE CASES
Find a device on the network by MAC or IP, whatever the reason
Helpdesk: "where is this plugged in?"
A user's PC has no network, a printer has moved, a phone has the wrong VLAN. The helpdesk searches the MAC or the IP and gets the switch, the port and the VLAN without calling the network team or walking to the wiring closet.
Security incident: isolate the compromised host
Your SOC gives you an IP address. In one search you know which switch port the machine is on, open a session on that switch from the Bastion and shut the port, with every command recorded.
Rogue device hunt
Filter by vendor to find the consumer access point or the unknown device someone plugged in, see on which port and VLAN it appeared and since when, and let Soron alert you the next time.
Moves, adds and changes
Before an office move or a switch replacement, list what is connected to each port. Afterwards, check that every device came back where it should, VLAN included.
Audits of connected endpoints
Export the endpoints seen per VLAN, per vendor or per switch to CSV, or answer "where was this device last Tuesday?" with the history of placements.
CAPABILITIES
Everything you need to locate a network device
The locator works on the MAC address tables, ARP tables and LLDP/CDP neighbours that ConnectMyAssets collects from your switches, routers and firewalls at every collection.
01
One search bar for MAC and IP addresses
Paste a MAC address in any spelling (aa:bb:cc..., aa-bb-cc..., aabb.ccdd.eeff), a MAC prefix, an IP address or the start of a network such as 10.1. Narrow by vendor, VLAN, switch, asset group or date range.
02
Exact location: the most probable port
A MAC address is seen by many switches along its path. ConnectMyAssets ranks the candidates and returns the single most probable port, with the switch, the VLAN and the IP address from the ARP tables.
03
Access port versus uplink, resolved
Ports that lead to another switch, router or firewall, recognised from LLDP/CDP neighbours and port-channels, are set aside. An IP phone or an access point behind a port does not count as an uplink: the device behind it is where the address is.
04
A confidence level you can trust
Every answer is rated high, medium or low with the reason in words: alone on its port and seen in the latest collection, behind a small unmanaged switch, or only seen on uplinks.
05
Vendor from the OUI database, offline
More than 54 000 IEEE vendor blocks are built into ConnectMyAssets. The vendor of every MAC address is resolved locally, without any call to the internet.
06
First seen, last seen and move history
Each placement of a MAC address on a port and VLAN is kept with its start and end. Pick a date range to see where a device was at that time, or open its page to follow all its moves.
07
Wi-Fi clients at their access point
A wireless client is located at the access point it is associated to, with the SSID, and the access point itself is placed on its switch port.
08
Scoped by permissions, exportable
Each user searches the asset groups their role allows. Each view exports to CSV or NDJSON with the filters applied.

HOW IT WORKS
How the locator finds the right switch port
For network engineers: the data used and the ranking applied, entirely computed on your infrastructure.
Data collected over SSH
At every collection, ConnectMyAssets reads the MAC address tables, ARP tables and LLDP/CDP neighbours of your network devices over SSH. No SNMP polling and no agent on the endpoints.
IP to switch port through ARP
An IP address is resolved through the ARP tables of your routers and switches to the MAC addresses behind it, then each MAC address is located on its port.
A ranking that favours edge ports
Links to other network devices come last. Among the remaining ports, the one where the address appears once on its switch and the port with the smallest MAC table win: an edge port holds a few addresses, an uplink holds many. The most recent sighting breaks ties.
History written only on change
A new placement opens when an address appears, moves to another port or changes VLAN, and closes when it leaves. Retention is 365 days by default and adjustable, up to ten years.
A PRACTICAL WORKFLOW
From a MAC address to a closed ticket
01
Collect
Your switches and routers are collected over SSH with credentials from the Vault.
02
Search
Type a MAC address, an IP address or a prefix in the locator.
03
Read the answer
Switch, port, VLAN, vendor, first and last seen, with the confidence and its reason.
04
Act
Open the switch in the Bastion, follow the history or set a Soron alert.
FAQ
Your questions, answered.
Prepare your project and define your scope.
How do I find which switch port a MAC address is connected to?
Without a tool, you follow the MAC address table from switch to switch until you reach a port that is not an uplink. ConnectMyAssets does it for you: type the MAC address in the locator and get the most probable access port, its switch and VLAN, with a confidence level and its reason.
How do I find a device on the network by its IP address?
Search the IP address: ConnectMyAssets looks it up in the ARP tables it collected, follows it to the MAC addresses behind it and locates each one on its switch port. You can also search the start of a network, such as 10.1, to list every device in it.
How does ConnectMyAssets tell an access port from an uplink?
A port is treated as an uplink when the switch reports, through LLDP or CDP, a neighbour that is a switch, router or firewall of your inventory; port-channels count as one link. Such ports are ranked last, so the answer is the port where the device is plugged in.
Can I locate a device behind an IP phone or an unmanaged switch?
Yes. A PC behind an IP phone is located on the phone's port with high confidence. Behind a small unmanaged switch, the port carries several addresses, so the answer is the right port with a medium confidence, and the reason says why.
Can I see where a device was connected in the past?
Yes. Every placement of a MAC address on a port and VLAN is kept with its first and last sighting, 365 days by default. Choose a date range to search the past, or open the address page to see all its moves.
How is the vendor of a MAC address identified?
From the IEEE OUI registries, more than 54 000 blocks compiled into ConnectMyAssets. The lookup runs locally and works on air-gapped networks.
Does the locator work with Wi-Fi clients?
Yes, for access points collected by ConnectMyAssets: a wireless client is located at its access point with the SSID, and the access point is placed on its switch port.
Who can use the locator?
Access follows your roles: each user searches the asset groups they are granted. A fleet-wide search permission exists for central teams, and every search beyond a user's own scope is written to the audit trail.
