Why is apipa being used?
Automatic Private IP Addressing (APIPA) is a DHCP fail-safe that protects a computer system from failure. It invokes a standby mechanism for local Internet Protocol version 4 (IPv4) networks supported by Microsoft Windows. With APIPA, DHCP clients can obtain IP addresses even when DHCP servers are not functional.
How do I remove apipa in Packet Tracer?
To disable APIPA, you can edit the registry to change the IP address to 0.0. 0.0 when no DHCP server is available. Start a registry editor and go to the HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesTcpipParametersInterfaces subkey. Select the string that identifies your adapter, and create a new DWORD Value.

How is DHCP affected by APIPA?
The APIPA provides the configuration to check for the presence of a DHCP server(in every five minutes, stated by Microsoft). If APIPA detects a DHCP server on the network configuration area, it stops, and let run the DHCP server that replaces APIPA with dynamically allocated addresses.
Why am I getting an APIPA address?
