IP Address Configuration 2-29
IP Address Configuration
This section describes how to assign an IP address to the bridge.
When the bridge has an IP address, you can remotely manage it
via Telnet, and will not need to go through the LinkBuilder MSH.
Telnet is a TCP/IP application. SNMP also requires the bridge to
have an IP address.
This simple configuration describes:
Setting up IP addresses
Using Telnet for remote connections
Using PING to test connections
Every IP network device is identifiable by its unique IP address
(Internet Protocol address). An extension to the IP addressing
scheme allows you to divide networks into subnetworks. The
subnet mask identifies which parts of the IP address denote the
network (network number) and which denote the host (host
number).
IP devices can only communicate with devices on different
networks via IP routers (gateways). A subnet mask is not needed
unless the network is IP routed.
If you have a private IP network, you can assign any IP address
you like. However, if you are connecting to the Internet, your IP
address must be unique. Network numbers can be assigned by
the Network Information Center (NIC). This organization assigns a
globally unique network number to each network that wishes to
connect to the Internet. The host numbers are then assigned by
your local system administration.
