Automatic Configuration (Apipa); Other Configuration - VSCOM netcom 123 User Manual

9.1.3. A C (APIPA)
UTOMATIC ONFIGURATION
A different type of automatic configuration is used by Windows. If the
stations are prepared for automatic settings, it will search for a DHCP
server (see above). But in SOHO networks this server might not exist.
Windows detects this failure, and the computer self-assigns an
IP-Address. This address is from the reserved LINKLOCAL block for
such purposes. The IP-Address is like 169.254.N.N, where N.N is from
0.1 to 255.254; the corresponding netmask 255.255.0.0 is mandatory.
The address is selected by random, and checked if already used.
The NetCom Devices do not support this method. However it is legal to
assign a static address from this range to the NetCom. Try to find an
unused address in you network, starting at 169.254.0.1. Check by PING
and ARP, if the address is used. If not, assign it to the NetCom.
This is only a workaround. The better solution is to install or configure
a simple DHCP server program. Typical SOHO Internet routers of
today already have such a server. Or you may change your network to
static configuration.
9.1.4. O C
THER ONFIGURATION
If the configuration of your computer differs from these examples,
strong reasons are likely. Ask your network administrator for proper
parameters in this situation.
