윈도우 10에서 사라진 "Adapters and Bindings" 네트워크 우선순위 조정 기능
예전에 네트워크 우선순위 조정에 대해 설명한 적이 있는데요.
다중 LAN 카드 환경에서 Dns.GetHostAddresses(local)가 반환해 주는 IP의 우선순위는 어떻게 될까요?

아쉽게도, Windows 10부터는 네트워크 설정의 "Advanced" / "Advanced Settings..." 메뉴로 뜨는 창에서 "Adapters and Bindings" 탭이 없어졌습니다.
Windows 10 Network adapter order doesn't "stick".

Cannot change Network Binding Order in Windows 10

위의 글에 보면 아쉬운 대로 해법이 나오는 데, InterfaceMetric 수치를 조정하라는 것입니다. (낮을수록 우선순위가 높습니다.)
따라서, 현재 여러분들이 컴퓨터에 바인딩 순서가 높은 순서를 보고 싶다면 다음과 같이 명령을 내리면 됩니다.
PS C:\> Get-NetIPInterface | where {$_.ConnectionState -eq "Connected"} | select ifIndex,InterfaceAlias,InterfaceMetric,AddressFamily,ConnectionState | sort InterfaceMetric | FT
ifIndex InterfaceAlias InterfaceMetric AddressFamily ConnectionState
------- -------------- --------------- ------------- ----
4 Ethernet 15 IPv4 ...d
11 WiFi 3 55 IPv4 ...d
1 Loopback Pseudo-Interface 1 75 IPv4 ...d
위의 경우 유선 Ethernet이 1순위이고, 이어서 무선 랜이 2순위입니다.
우선순위를 조정하고 싶다면 InterfaceMetric 수치를 변경해야 하는데,
아래의 코드는 이를 쉽게 해주는 PowerShell 스크립트입니다.

# Purpose: Manually set the Binding Order (order of preference) for a specified Network Interface
#
# Written by: Joshua D. True
#
# Notes: This script has been set to only show interfaces with an active connection (to avoid confusion dealing with unused virtual interfaces)
# To change the script to show all interfaces, remove the following ### | where {$_.ConnectionState -eq "Connected"} ### from both lines
# of code that begin with "Get-NetIPInterface"
# This script requires Admin elevation!

# Display active interfaces to be changed

# Prompt user for index and new metric value of an interface
$nicIndex=Read-Host "Enter the Index of the network connection that you would like to change"
$nicIMetric=Read-Host "Enter the new Interface Metric value to be assigned to the Index you just selected (lower number means higher priority)"
