Every time Windows virtual machine restarts a new mDNS record begins multicasting from the Mac with hostname
localhost_prl and IP
As a result when it happens another record is added.
After killing mDNSResponder process on the Mac the issue disappears but only until the next Windows restart.
As a temporary workaround disable Windows virtual machine reverse sharing by opening the machine's configuration > Options > Sharing > Share Windows > disabling Access Windows folder from Mac.
