Addressing 1

Octel Overture 200/300 Serenade 3.0

the
network portion for the class B address gives the following in binary format:
1111111
1 1
111111
1 1
111
1000 00000000
This is equivalent to
255.255.248.0
which is what the user would enter in reply to the UPDA
TE question:
Enter the subnet mask for this Digital Network (Default
255.255.0.0):255.255.248.0
Example
2
— Assume that the system administrator in this network wants to divide the network into 256
subnetworks having at most 256 hosts in each subnet. T
o represent 256 subnets requires 8 bits of subnet
mask information that need to be set to 1:
1111111
1 1
111111
1 1
111111
1 00000000
This is equivalent to
255.255.255.0
which is what the user would enter in reply to the UPDA
TE question:
Enter the subnet mask for this Digital Network (Default
255.255.0.0):255.255.255.0
Example
3
— Digital networking used for uniform numbering plan domain or multicabinet systems only
.
If there is only one physical network, the system administrator may choose not to use subnets.
If there is no connectivity to any other InterNetworking device, any IP address may be used. However
,
using a class C address (i.e., some number in the range 192.0.0.0 – 223.255.255.254) is usually suitable.
For example, for three Octel Overture 200/300 cabinets on their own dedicated LAN segment, the IP
addresses might be
Cabinet 1 — 192.0.0.1
Cabinet 2 — 192.0.0.2
Cabinet 3 — 192.0.0.3
If you choose a class A address in the absence of subnets, set the subnet mask to 255.0.0.0.
If you choose a class B address in the absence of subnets, set the subnet mask to 255.255.0.0.
If you choose a class C address in the absence of subnets, set the subnet mask to 255.255.255.0.
For example, if your IP address is 192.1.2.3, your subnet mask would be 255.255.255.0.
