APIPA and Link-Local Addressing
PX3TS supports Automatic Private Internet Protocol Addressing (APIPA).
With APIPA, your PX3TS 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 PX3TS using the
link-local address/host name. Those in a different subnet cannot access it.
Exception: PX3TS in the Port Forwarding mode does not support APIPA. See
Setting the Cascading Mode (on page 328).
Once the PX3TS 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 PX3TS, but no IP address is assigned to the PX3TS.
This may be caused by the absence or malfunction of DHCP servers in the
network.
Note: Configuration by connecting the PX3TS to a computer using a
network cable is an application of this scenario. See
Connecting the PX3TS
to a Computer (on page 23).
