Protocol Addresses
IPX Addresses
If you are using the IPX protocol, the Module will be allocated an IPX
address automatically by the local IPX router or NetWare File Server.
This happens approximately 60 seconds after the unit is powered up
for the first time. You should never need to change the allocated
address.
IP Addresses
IP (Internet Protocol) addresses have the format n.n.n.n where n is a
decimal number between 0 and 255. An example IP address is:
192.168.100.120
IP addresses are made up of two parts:
■
The first part (192.168 in the example) identifies the network on which
the device resides. Network addresses are assigned by three
organizations. Depending on your location, each organization assigns
a globally unique network number to each network that wishes to
connect to the Internet.
■
The second part (100.120 in the example) identifies the device within
the network. Assigning unique device numbers is your organization's
responsibility.
If you are unsure of the IP addresses allocated to you, consult your
network administrator. If you do not have an Internet address, see
“Obtaining a Network Number” on page A-6.
If you are the manager of a network that has no connections to the
outside world, you may not be aware of the network address. If you are
not using the IP protocol for anything other than network
management, you may use arbitrary addresses. We suggest you use
addresses in the series 192.168.100.Y, where Y is a number between 1
and 254. Use 192.168.101.Y for the SLIP address (192.168.101.1 is the
default setting) . Remember that no two devices on a network may
have the same address. If you later connect to the outside world, you
must change all the arbitrary IP and SLIP addresses, to comply with
