the DHCP/BOOTP server contains in addition to the IP

LAN-Modem immediately loads this information into its
non-volatile memory.
To start up the LAN-Modem in DHCP/BOOTP networks,
consult with your systems administrator. If you are
assigning the address using DHCP, please indicate that
a reserved IP address is needed. For the purpose of
