After changing the IPv6 prefix in the virtual network manager in VMWare Workstation, I ended up with a dangling ip address and I wondered how I could get rid of it. When trying `netsh delete address "VMware Network Adapter VMnet8" fd20:XXXXXX` it told me that the command was not found. **It turns out, you have to explicitly tell netsh that you're talking about an ipv6 address:** ```powershell netsh int ipv6 delete address "VMware Network Adapter VMnet8" fd20:XXXXXXXX ``` Remember to run this on a cmd as an Administrator, otherwise you get a confusing error saying *"The system cannot find the file specified"*.
