Comparing IPv4 Addresses to Determine Network Membership for Host-A in Computer Science: A Step-by-Step Guide

Host-A has the IPv4 address and subnet mask 10.5.4.100, 255.255.255.0, Which of the following IPv4 addresses would be on the same network as Host-A? (Choose all that apply) A)10.5.4.1 B)10.5.0.1 C)10.5.4.99 D)10.0.0.98 E)10.5.100.4

To determine which of the given IPv4 addresses are on the same network as Host-A, we need to compare their network addresses based on the subnet mask.

In this case, the network address of Host-A can be calculated by performing a bitwise AND operation between the IPv4 address and the subnet mask.

For Host-A:
IPv4 address: 10.5.4.100
Subnet mask: 255.255.255.0

Performing the bitwise AND operation, we get the network address:
10.5.4.100 : 00001010 . 00000101 . 00000100 . 01100100
AND 255.255.255.0 : 11111111 . 11111111 . 11111111 . 00000000
————————————————————
Network address: 10.5.4.0 : 00001010 . 00000101 . 00000100 . 00000000

Now, let’s compare the network addresses of the given IPv4 addresses:

A) 10.5.4.1 : 00001010 . 00000101 . 00000100 . 00000001
B) 10.5.0.1 : 00001010 . 00000101 . 00000000 . 00000001
C) 10.5.4.99 : 00001010 . 00000101 . 00000100 . 01100011
D) 10.0.0.98 : 00001010 . 00000000 . 00000000 . 01100010
E) 10.5.100.4 : 00001010 . 00000101 . 01100100 . 00000100

By comparing the network addresses with the network address of Host-A (10.5.4.0), we can determine which IPv4 addresses belong to the same network:

A) 10.5.4.1 : Belongs to the same network as Host-A
B) 10.5.0.1 : Does not belong to the same network
C) 10.5.4.99 : Belongs to the same network as Host-A
D) 10.0.0.98 : Does not belong to the same network
E) 10.5.100.4 : Does not belong to the same network

Therefore, the IPv4 addresses that are on the same network as Host-A are A) 10.5.4.1 and C) 10.5.4.99.
