@digitalFounders i did not know, that this was missing and simply assumed that all the named given to clients in the dhcp would autoatically be resolved - boy was i shocked to find that that feature...

In my Omada-Controller i gave the HCP entry 10.0.0.48. The Cam stil switches over to 10.0.0.111 by itself 1-2 times a week. A restart fixes that. but why?
