You have a Windows virtual machine, and you want your machine to be reachable by other VMs; however, you need to ensure this new machine has a static IP. To do that, use the commands below.
# Set a static IP to the Ethernet 1 adapter with /24 subnet mask, leaving the last octet to host addresses
New-NetIPAddress -InterfaceAlias "Ethernet 1" -IPAddress 192.168.254.110 -PrefixLength 24
# Get the IPv4 configuration of the interface; it should show the IP address set by the previous command
Get-NetIPAddress -InterfaceAlias "Ethernet 1" -AddressFamily IPv4
