Question : IP tools capture packets for other LAN nodes

Good Day Experts!

I have been using IP tools to capture packets in and out of my computer.
I just noticed when capturing packets that i can see all the packets coming in and out from another LAN machine on my network in this case "192.168.7.72"
My machine is "192.168.7.2".  The LAN is behind a router and switch.  The other LAN computer is listening to radio broadcasts from the BBC but i can see all the packets to and from this conncetion from my computer.  Why are packets that are meant for other LAN computer seem to be bouncing off my NIC?

I should have no network traffic really as i am doing nothing on WAN or LAN (except EE)  but i have a steady steam of constant 5000 packets that are not even coming to my computer.

A pic of some of what IP tools is reporting to me.  (This is from the 192.168.7.2 machine)

Answer : IP tools capture packets for other LAN nodes

You said you're "...behind a router and switch..."

Did you by any chance mean a router and a hub?

This behavior is exactly what you would see if you were using a hub to connect multiple PC's.
