102, 104 and 105 are our iphones and ipad. i can't imagine what 108 is.

how do i figure out what it is? could it be hurting my computer?

I have the IPScanner because I'm trying to instail the wireless IP camera from smarthome.
I've got the camera talking to my router. Still working on figuring the settings so I can dial up the camera over the web.

:)

thanks for any ideas!
