Choosing IP Addresses
If yo ur VN- C OM M A N DE R co m pu ter an d V N
Processor(s) are directly connected or connected via their
own independent network, follow the guidelines below
for choosing your IP Address(es).
However, if you intend connecting your computer and
VN Processor(s) to an existing network, you will need to
advise the network administrator and ask them to
allocate suitable addresses to you.
On an independent network you can (in theory) use just
about any addresses you wish. However, it is generally
recommended that you use the Class C format (i.e. from
192.0.0.1 up to 223.255.255.253).
Remember that there are two rules for choosing IP
Addresses:
• the network identifier must be the same for each
address, and
• the host identifier must be unique for each address.
Applying these rules to Class C addresses, it can be seen
that the first three decimal values of your IP Addresses
must all be the same, while the last value is used to
uniquely identify each device.
The following is an example of a valid Class C addressing
scheme:
Device IP Address
VN-COMMANDER Computer 208.132.180.41
VN Processor 1 208.132.180.42
VN Processor 2 208.132.180.43
NOTE: The host identifiers (e.g. 41, 42, and 43 in the above
example) need not be sequential or in any particular order.
However, it is recommended that you group the numbers for
simplicity.
