A thought: Creating and configuring the "vEthernet (WSL)" network adapter at boot time.

[Myron-S]

Something I'm looking at, but someone may already have a solution to share with everyone.

When WSL2 starts it creates a virtual adapter named "vEthernet (WSL)" and assigns it some random IP address. When WSL is shutdown the virtual network adapter remains with all its settings intact. When WSL is cold-started again then that virtual adapter's settings are utilised. Same IP addresses and settings. These are lost when Windows 10 OS is shutdown.

Is there a way using PowerShell to create and pre-configure "vEthernet (WSL)" with all the desired settings so when the Windows 10 OS starts. "vEthernet (WSL)" is already there and does not need to be re-created when WSL2 kernel cold-starts.

This would get round guest machines having to deal with changing local network addresses after every start-up of Windows 10.

Effectively, this gives the WSL2 guest OS a permanent static IP address and always be on the same subnet. I guess this would also work with IPv6.
