The usual cause of this for most people is that they've rebooted their router and it kept the leases in memory, so it isn't aware it assigned the IP to multiple computers. Really, automatically renewing the lease if you're on DHCP is probably the best behaviour for a home/simple OS. For computers on a network administered by professionals, it should be possible to disable this (and other automatic) behaviour.
Does anyone know what the iPhone/iPad/etc. do in this case?
- merlincorey 14y agoThe iDevices all bounce around getting multiple addresses within the DHCP range. Last time I was administrating an office network full of iDevices I had to increase the DHCP range to account for the iDevice's bouncing all over the range and using up addresses pretty needlessly.
- jlgaddis 14y agoMost sane DHCP servers will also attempt to ping an IP address before offering it (and won't offer it, of course, if it gets a response).
