Address ranges
The following addresses will never appear on the Internet and are thus free for use in your private network.
–10.0.0.0
–172.16.0.0 through 172.32.0.0
–192.168.0.0 through 192.168.255.0
If you pick one of these you should have no address problems with the internet.
Boot Protocol (BOOTP)
This protocol was invented when it was expensive to store software or configurations in small units (and even more expensive to upgrade them) so when the unit was switched on it would ask (broadcast) on the LAN for its software. A machine with a disk would reply and send it. Typically a BOOTP Server would send a file to the unit using Trivial File Transfer Protocol (TFTP). The IPNC uses BOOTP to obtain new versions of its operational software (which it stores in its flash memory). It also uses TFTP to send and receive configuration files.
The manager program also acts as a BOOTP server. Using the File menu, and selecting BootP, it is possible to configure the IP Address to be given to the IPNC and the software filename to be sent (typically nadicii.bin). Normally this table is configured automatically by other actions in the manager. The BootP server recognizes the IPNC by its MAC address this is a hardware address built into the unit at manufacture. It is in the form 00e007xxxxxx. The TFTP log in the manager may give clues when you are having problems sending new software to a unit.
