Enter Address Space:
Type 10.1.0.0/16 for the IPv4 address space.

Number of Addresses:
This address range provides a total of
65,536 addresses IP addresses for the Virtual Network.
The following image shows that 10.1.0.0/16 provides
65,536 addresses addresses within this network.

Visual Aid
Below is an illustration of how the 10.1.0.0/16 address space is organized:

IP Range Total Addresses
10.1.0.0 - 10.1.0.255 65,536 addresses

Subnet Name:
Provide a unique name for the subnet, such as Subnet-1, Subnet-2, etc.
Subnet Address Range:
Define the IP range for the subnet within the 10.1.0.0/16 address space. For example, you might use 10.1.1.0 - 10.1.1.255 for one subnet and 10.1.3.0 - 10.1.3.255 for another. Ensure the ranges are within 10.1.0.0 - 10.1.0.255
