Question

Your company has a policy to use the first IP address in a network as the default gateway address. You have been instructed to configure a new server with an IP address of 192.168.184.227 and a subnet mask of 255.255.255.248.

What is the network address for this network?

What is the default gateway for this server?

Reflection Why is the subnet mask important in determining the network address?

Answer 1

1a)

Network address for this network = 192.168.184.224

Given IP is : 192.168.184.227 = 11000000. 10101000 .10111000.11100011

Subnet mask : 11111111.11111111.11111111.11111000

If we apply AND operation between given ip and subnet mask we get "network address".

After applying AND operation we get

11000000.10101000.10111000.11100000

= 192.168.184.224

2a)

Given ip is :192.168.184.227

So,the first ip is default gateway.

Default gateway for this server = 193.168.184.225

3a)

Because ,the subnet mask provides the number of bits to use for the network portion of an address. The network address cannot be determined without it.
