Question
Assume that you have been assigned a classless network address of 201.143.156.0/22.
a.If no subnets are defined for this network, what is the maximum number of hosts that can be defined in the network? Why?
b. What is the binary representation of the network address?
c. What is the network mask for this network in binary and in decimal?
-Assume you decide to use four of the host bits to define subnets within the network:
d. How many subnets could be defined?
e. What would the subnet mask be?
f. How many hosts could be defined within each subnet? Why?
g. Create a table for every subnet that could be created. List the following in the table:
i. The subnet address
ii. The range of host addresses that could be assigned within the subnet.
iii. The broadcast address for the subnet
Explanation / Answer
Solution:
a to f are done as per Chegg guidelines, please repost the rest.
a)
In the given IP address 201.143.156.0/22. which is CIDR, 22 bits are used for network address
and rest = 32-22= 10 bits are for a host address
maximum number of hosts which can be assigned are
2^10-2= 1022
2 hosts which are subtracted are the subnet ID and the broadcast address of the network.
b)
The binary representation of the network address is
11001001.10001111.10011100.00000000
c)
Network mask in binary
11111111.11111111.11111100.00000000
in decimal
255.255.252.0
d)
Number of subnets that can be defined is
2^4= 16 subnets
e)
255.255.255.192
f)
Number of hosts that can be defined are
out of 10 bits, 4 is taken for the subnet division rest are 6 bits
Number of hosts possible = 2^6*2 = 62 hosts
