[QUOTE="Brian jojade, post: 88961, member: 211"] Re: Apple Airport Express + DSP A device will start to attempt a lease renewal at 50% of the lease time. So, if you have a lease set at 1 day, in 12 hours, the device will start requesting from the server to renew that lease. If the DHCP server doesn't respond, it will continue to request, in shorter intervals, until which time the lease expires. When that happens, the device will look for other DHCP servers on the network to provide it an IP address. It will continue to use the leased address until it expires, unless manually told to renew. Rebooting a device will trigger a renew of a lease. Some devices will trigger a renew of lease after waking from sleep as well. Many devices will remember their previous DHCP server and try to ask that server first for a renewal, thus maintaining the same IP address. But if it can't find that DHCP server on reboot, it will then accept DHCP offers from any server. The only real way to end up with network conflicts is to have a device powered up, and then switch the network that it's on without restarting or releasing the existing lease. Not too likely a problem with an audio system setup. [/QUOTE]
