How to determine physical location of an IP address.
I have a Procurve 2524 switch and need to find out what port an IP address is using. How do I do this?

Doesn't make sense. IP addresses on a computer use all the different ports that are needed for the different services like web browsing (80 and 443), email (25, 110, 465, 587, 995) and FTP (20, 21, and other 'random' ports).

I have an IP address showing up on my network for a device that I don't know where it came from. I'm trying to determine where it's connected and thought if I could find out what port it's showing up on the switch, I can track it back to the physical location in the building.
So you want to know the Physical port, not the TCP service port, that it's connected to.
Is it showing up in DHCP or have a static? Could be a phone connected to wireless, does it have a device name?

It's showing up in DHCP and does have a device name.

Thanks for you help.
Switches / Hubs
A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.
