You can add a Subnet in your Virtual Network but first need to create Address Space.

This can be done here - Virtual Network>Address Space>Add Additional Address Range>Save

Now you can use this new address space to create a Subnet.

Virtual Network>Subnet>Name, your new Address Range will be displayed here>OK
