Pinged computer names don't match actual computer IP address?
To get the IP addresses (local) of each other, we'd ping the computer name of the person we wanted, the computer name being clearly visible on each of our mac books.
From time to time, IP addresses would change, but that's not really much of a problem.
Thing is, for a few people, their actual IP address is different to what we'd get when we ping them, and hence we'd accidentally end up in someone else's mac book instead of the one we intended.
Does anyone have a clue as to what is going on here? Or a solution? (Other than getting them to go and find their IP addresses with "ifconfig" or through terminal?)
We're using OS X 10.6.4, btw
