Network ID and Broadcast ID Description

Network ID

Network ID is a part of IP address that is used for recognizing devices or person on a network such as the internet.

Broadcast ID 

A Broadcast ID is a logical address of a network used to connect devices of a multiple access network. If you sent a message through a broadcast ID it will be received by all the hosts of that network.

So how can we find the network ID and the broadcast id of a subnet. We have been given an IP address 200.1.10.0 which require 16 subnets and also the network ID and the Broadcast ID of the first subnet. Here are the following steps

200.1.10.0

require 16 subnets

so 2^4 =16 so 4 is the required value 

first we write the table 

128      64      32      16      8      4      2       1

Now we insert the value in the table

128      64      32      16      8      4      2       1 

  1         1        1        1       0      0      0       0
so we know that the range of each IP will be 16 and the first subnet range is as follows 
200.1.1.0
200.1.1.1
200.1.1.2
       *
       *
200.1.1.14
200.1.1.15
So the Network ID and the Broadcast ID from the range is
200.1.1.0 ---------> Network ID
200.1.1.15--------> Broadcast ID 
       
Here is another question to clear your Concept

212.5.9.0/24
require 4 subnets

Sol

so 2^2 =4 so 2 is the required value 

first we write the table 

128      64      32      16      8      4      2       1

Now we insert the value in the table

128      64      32      16      8      4      2       1 

  1         1        0        0      0      0      0       0
so we know that the range of each IP will be 64 and the first subnet range is as follows 
200.5.9.0
200.5.9.1
200.5.9.2
       *
       *
200.5.9.62
200.5.9.63

The Network ID and the Broadcast ID from the range is
200.5.9.0 ---------> Network ID
200.5.9.63--------> Broadcast ID
