4. APIPA stands for Automatic Private Internet
Protocol Address.
APIPA is a feature of windows based OS that
enables a device to automatically self-
configure with a Private IP address.
A private IP address is one which is assigned to each device to
communicate with other devices in a LAN.
5. APIPA uses a Class B IP address that ranges
from 169.0.0.0 - 169.255.255.254 with
subnet mask of Class B i.e 255.255.0.0
IANA has reserved this range for APIPA.
6. APIPA is used to assign IP address to those
devices who wants to communicate with
other one’s in a LAN, when DHCP is
unreachable.
APIPA overcomes the DHCP server failure.
7. Device who wants to communicate sends a
discover message to DHCP.
If DHCP fails then the device self-configured
with an IP address.
ARP is used to check address conflict occurs
or not.
Simultaneously, the client lookup for DHCP.
If DHCP is available, then it update the
addresses automatically by replacing the
present one.
19. APIPA is enabled by default in windows
whenever the device network interface is
configured for DHCP.
APIPA can be disabled by editing the window
registry setting value to 0.
For disabling it, type ctrl+R and write
“regedit”.
