Question

Are these two IP addresses on the same network? . 150.140.130.120/25 . 150.140.130.130/25 A True B False Question 30 Are these two IP addresses on the same network? . 200.17.101.231/23 • 200.17.100.14/23 A True B False

Answer 1

If two IP addresses belong to same network it means that their Network IDs are same.

1) True

Reason:

The Given Two IP addresses are 150.140.130.120/25 and 150.140.130.130/25

These IP addresses belongs to class B because their first octet is 150 and the range of class B IP addresses is 128 to 191.

In class B IP the first 2 octets are network ID and the next 2 octets are host ID. Here the network ID of first IP address is 150.140.

And the network ID of second IP address is 150.140. Both the network IDs of the IP addresses are same.

And both the IP addresses have same subnetmask. So, The answer is the two IP addresses belongs to same network.

2) False

Reason:

The Given Two IP addresses are 200.17.101.231/23 and 200.17.100.14/23

These IP addresses belongs to class C because their first octet is 200 and the range of class C IP addresses is 192 to 223.

In class C IP the first 3 octets are network ID and the next 1 octet is host ID. Here the network ID of first IP address is 200.17.101.

And the network ID of second IP address is 200.17.100.

Both the IP addresses have different network IDs, so they belong to different networks.

The answer is the two IP addresses belongs to different network.
