APIPA and Link-Local Addressing
PX3 supports Automatic Private Internet Protocol Addressing (APIPA).
With APIPA, your PX3 automatically configures a link-local IP address
and a link-local host name when it cannot obtain a valid IP address from
any DHCP server in the TCP/IP network.
Only IT devices connected to the same subnet can access the PX3 using
the link-local address/host name. Those in a different subnet cannot
access it.
Exception: PX3 in the Port Forwarding mode does not support APIPA.
See
Setting the Cascading Mode (on page 304).
Once the PX3 can get a DHCP-assigned IP address, it stops using APIPA
and the link-local address is replaced by the DHCP-assigned address.
Scenarios where APIPA applies:

DHCP is enabled on the PX3, but no IP address is assigned to the
PX3.
This may be caused by the absence or malfunction of DHCP servers
in the network.
