unknown · Answer

APIPA. (Automatic Private IP Addressing) The Windows function that provides DHCP autoconfiguration addressing. APIPA
 assigns a class B IP address from 169.254.0.0 to 169.254.255.255 to the
 client when a DHCP server is either permanently or temporarily 
unavailable.

if your devices are ending up with APIPA series 169.254.X.X then indicates local network issues. If answer no then there may be another unknown DHCP server in the network which need to be looked at .
