Question

Use the following network address: 172.192.0.0/10 to create four (4) different /12 subnet addresses.

• Identify the range of IPv4 addresses.
• Identify the broadcast address for each of the above subnet addresses.

Answer 1

IP Address:

An IP address is an identifier or label used to identify a machine on the internet or a particular network. Each of the devices on the internet must have an IP address for identification.

IPv4 is the first version of Internet Protocol that uses a 32-bit address and this protocol is most widely used.

Total number of IP address supported by IPv4 = 2³²

The netmask and subnet mask is used to divide the IP address as given below:

The netmask is a sequence of '1' followed by a sequence of '0' and it is used to divide an IP address into multiple subnets.

The subnet mask is a sequence of '1' followed by a sequence of '0' and it is used to separate a big network into smaller multiple networks.

The given network address is:

172.192.0.0/10

To create four subnets, we need 2² = 4 more bits for network id.

The first subnet starting address is = 172.192.0.0

The first subnet end address is = 172.207.0.0

The broadcast address of the first subnet is = 172.207.0.0

The second subnet starting address is = 172.208.0.0

The second subnet end address is = 172.223.0.0

The broadcast address of the first subnet is = 172.223.0.0

The third subnet starting address is = 172.224.0.0

The third subnet end address is = 172.239.0.0

The broadcast address of the first subnet is = 172.239.0.0

The fourth subnet starting address is = 172.240.0.0

The fourth subnet end address is = 172.255.0.0

The broadcast address of the first subnet is = 172.255.0.0
