Hyper-V Default switch IP address range change. Ver 1809 Build 17763.1

southernprogrammer Thanks, gived myself permission to tweak a litlle you script to update all my vmdomains's ip also, work like a charm.

I also think the behavior of the default adapter is not logical, and i personaly see it as a bug, i hope it get fixed since i am migrating from VmWare to Hypre-V, streamlining my setup accross multiple device is better without scripts...

HotCakeX I'm talking about accessing a url that is hosted inside the guest.

If doing development you could do remote debugging on your host while having your environment on your guest.

Thanks, but Hyper-V VMs with enhanced session allow drag and drop between guest and host.

or is the script for a specific situation only?

If you just need to access resources on your guest from the host, you could just have a powershell script that you can run on the host after launching the VM.

Replace 'BryanDev' with the name of your VM and replace "weirdalvm.3-gis.com" with your desired url you want to access the resource with.

Run as administrator

$result = get-vm -Name BryanDev | Select -ExpandProperty Networkadapters | Select IPAddresses | ft -hidetableheaders | Out-String
$result = $result.Split(",")[0].Trim().Replace("{", "").Replace("}", "")
