Thanks jdsilva, not all clients are Windows and we can't use DNS for this. Trying to understand why there is such variability between different API calls that retrieve the client IP address and also trying to understand the process timers for collection of this info.    e.g. the MS switch detects the client IP within X secs (immediately? assume it's via dhcp snooping but not sure) MS switch updates internal tables after X seconds (ie, radius accounting only returns the correct client IP after several minutes) MS switch updates Meraki cloud database every XX seconds Dashboard updates from database every XX seconds API - network - clients updates every XX seconds API - org - clients updates every XX seconds   Thanks Steve   ...
