APIPA and Link-Local Addressing
The 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 282).
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 24).
The PX3TS previously obtained an IP address from the DHCP server,
but the lease of this IP address has expired, and the lease cannot be
renewed, or no new IP address is available.
Link-local addressing:
IPv4 address:
Factory default is to enable IPv4 only. The link-local IPv4 address is
169.254.x.x/16, which ranges between 169.254.1.0 and
169.254.254.255.
IPv6 address:
A link-local IPv6 address is available only after IPv6 is enabled on the
PX3TS. See
Configuring Network Settings
(on page 269).
Host name - pdu.local:
You can type
https://pdu.local to access the PX3TS instead of typing
the link-local IP address.
