Which is the valid broadcast ID for the IP address 22.214.171.124 with a subnet mask of 255.255.255.128?
126.96.36.199 is the valid broadcast ID for the IP address 188.8.131.52 with a subnet mask of 255.255.255.128. The valid range for the IP address 184.108.40.206 with a subnet mask of 255.255.255.128 is 220.127.116.11 – 18.104.22.168. The subnet ID is 22.214.171.124.
Subnetting allows you to split single and large subnets defined by Class A, B, and C IP addresses into multiple subnets with smaller IP address host ranges. Subnetting allows efficient use of IP addressing space, which has become a scarce resource.
To subnet an existing network, you will use host bits to split the IP address into multiple logical subnets. For example, if you use three bits of the host ID for subnetting, you have created 23 = 2 x 2 x 2 = 8 subnets. Remaining bits of the host ID in decimal form will form the number of hosts on each subnet.
All other options are incorrect as these IP addresses fall in other subnets.
126.96.36.199 is the network ID for the next subnet created when using a mask of 255.255.255.128 on the class C network 188.8.131.52. The following network IDs are created when you use a mask of 255.255.255.128 on the class C network 184.108.40.206:
– 220.127.116.11 – Valid range 18.104.22.168-22.214.171.124, 126.96.36.199 is the broadcast
– 188.8.131.52 – valid range 184.108.40.206-220.127.116.11, 18.104.22.168 is the broadcast
22.214.171.124 and 126.96.36.199 are both valid addresses in the second subnet created, that is, the 188.8.131.52 network.
