⟩ Tell me what does APIPA stand for and how can you tell if your computer is using it? why would your computer be using it?
APIPA - Automatic Priavte IP addressing.
This is a dynamic service (I mentioned here dynamic means you have not need to start & stop this service, computer will automatically started this service when DHCP is down & stop this service when DHCP is up) that means this service is related with DHCP.
APIPA assign private IP address from 169.254.0.1 to 169.254.255.254.
APIPA also check presence DHCP server every 5 miniute ( according to microsoft )
