To subnet the given Class C network address (192.168.19.0), we can use the concept of CIDR (Classless Inter-Domain Routing) notation to divide the network into smaller subnets.
Before we start subnetting, let's first understand the structure of a Class C network address. In a Class C network, the first three octets (192.168.19) are the network portion, and the last octet (0) is reserved for host addresses.
To accommodate all the required needs, we need to determine the number of subnets and the number of hosts per subnet.
Let's assume we need 4 subnets and each subnet requires 30 hosts.
Step 1: Determine the number of subnet bits:
To accommodate 4 subnets, we need at least 2 subnet bits. (2^2 = 4
Step 2: Calculate the subnet mask:
Since we are using 2 subnet bits, the subnet mask will be /26 (32 - 2 = 30). In binary, the subnet mask is 11111111.11111111.11111111.11000000, which translates to 255.255.255.192 in decimal notation.
Step 3: Divide the network into subnets:
Using the subnet mask /26, we can divide the network into 4 subnets. The subnet ranges for each subnet are as follows:
Subnet 1:
- Network address: 192.168.19.0
- Broadcast address: 192.168.19.63
- Usable host addresses: 192.168.19.1 to 192.168.19.62
Subnet 2:
- Network address: 192.168.19.64
- Broadcast address: 192.168.19.127
- Usable host addresses: 192.168.19.65 to 192.168.19.126
Subnet 3:
- Network address: 192.168.19.128
- Broadcast address: 192.168.19.191
- Usable host addresses: 192.168.19.129 to 192.168.19.190
Subnet 4:
- Network address: 192.168.19.192
- Broadcast address: 192.168.19.255
- Usable host addresses: 192.168.19.193 to 192.168.19.254
Each subnet can accommodate 62 hosts (2^6 - 2), which is more than the required 30 hosts per subnet.
Therefore, the IP address and subnet mask for each device in the picture would depend on which subnet each device belongs to. Based on the given information, we can assign IP addresses from the usable host address ranges mentioned above to each device.
Please note that the specific IP addresses for the devices in the picture are not provided, so it is not possible to provide exact IP addresses for each device. However, using the subnet ranges provided, you can assign IP addresses from those ranges to the devices in a way that meets the requirements of the network.
