Question

1. Given the network named: 192.168.1.0 /24:

a. What is the first valid host address?

b. What is the last valid host address?

c. What is the broadcast address?

Answer 1

Network : 192.168.1.0/24

a)
here 24 bits are for network,
therefore, 8 bits are for hosts.

-->converting last 8-bit to binary
i.e 192.168.1.00000000 <------------ this is the network id of the given network.

Finding First Valid Host address:
192.168.1.00000001 <------------------this is the first valid host address
i.e 192.168.1.1 (converted to decimal)

b)
similarly,
Finding Last Valid Host address:
192.168.1.11111110 <------------------this is the last valid host address
i.e 192.168.1.254 (converted to decimal)

c)
Finding Broadcast address:
192.168.1.11111111 <-------------------this is the broadcast address
i.e 192.168.1.255 (converted to decimal)
