Windows PowerShell \u00a0common networking commands (IPCONFIG, PING, TRACERT, ROUTE NSLOOKUP,NETSTAT)<\/span><\/strong><\/span><\/h1>\n

Network Engineer to trouble shoot some of Windows Servers issue apart from Networking Devices. Maybe you need to check the IP address of a machine or test if its networking connection is working. Maybe you need to see if DNS is properly configured or check the latency between two hosts.<\/p>\n

If you have been in this field long enough, you probably have a few favorite commands that you learned years ago and use on a regular basis, like IPCONFIG or PING.<\/p>\n

There are literally hundreds of networking-related PowerShell cmdlets in Windows these days. Just try out this command on your machine:<\/p>\n

Get-Command -Module Net* | Group Module \u00a0 – Give you all the list available in your Windows Servers or Windows 10<\/strong><\/p>\n

\"\"<\/p>\n

But more important than knowing every one of them, is to know the most useful cmdlets that have the potential to replace those old commands that you can\u2019t live without.<\/p>\n

Only PowerShell can do that you\u2019ll find amazing new troubleshooting abilities\u2026<\/p>\n

IPCONFIG<\/h3>\n

Description: This command has many options, but the most common usage is just to show the IP address, subnet mask and default gateway for each network adapter in a machine.<\/p>\n

PowerShell: Get-NetIPConfiguration or Get-NetIPAddress<\/p>\n

Sample command lines:<\/p>\n

    \n
  • Get-NetIPConfiguration<\/li>\n
  • Get-NetIPAddress | Sort InterfaceIndex | FT InterfaceIndex, InterfaceAlias, AddressFamily, IPAddress, PrefixLength -Autosize<\/li>\n
  • Get-NetIPAddress | ? AddressFamily -eq IPv4 | FT \u2013AutoSize<\/li>\n
  • Get-NetAdapter Wi-Fi | Get-NetIPAddress | FT -AutoSize<\/li>\n<\/ul>\n

    \"\"<\/p>\n

    PING<\/h3>\n

    Description: Checks connectivity to a specific host. Commonly used to check for liveliness, but also used to measure network latency.<\/p>\n

    PowerShell: Test-NetConnection<\/p>\n

    Sample command lines:<\/p>\n

      \n
    • Test-NetConnection www.google.co.uk<\/li>\n
    • Test-NetConnection -ComputerName www.google.co.uk -InformationLevel Detailed<\/li>\n
    • Test-NetConnection -ComputerName www.google.co.uk | Select -ExpandProperty PingReplyDetails | FT Address, Status, RoundTripTime<\/li>\n
    • 1..10 | % { Test-NetConnection -ComputerName www.microsoft.com -RemotePort 80 } | FT -AutoSize<\/li>\n<\/ul>\n

      \"\"<\/p>\n

      NSLOOKUP<\/h3>\n

      Description: Name server lookup. Mostly used to find the IP address for a given DNS name (or vice-versa). Has many, many options.<\/p>\n

      PowerShell: Resolve-DnsName<\/p>\n

      Sample command lines:<\/p>\n

        \n
      • Resolve-DnsName www.cisco.com<\/li>\n
      • Resolve-DnsName www.cisco.com -type SOA<\/li>\n
      • Resolve-DnsName cisco.com \u00a0-Server 8.8.8.8 \u2013Type A<\/li>\n<\/ul>\n

        \"\"<\/p>\n

        \"\"<\/p>\n

        ROUTE<\/h3>\n

        Description: Shows the IP routes in a given system (also used to add and delete routes)<\/p>\n

        PowerShell: Get-NetRoute (also New-NetRoute and Remove-NetRoute)<\/p>\n

        Sample command lines:<\/p>\n

          \n
        • Get-NetRoute -Protocol Local -DestinationPrefix 192.168*<\/li>\n
        • Get-NetAdapter Wi-Fi | Get-NetRoute\n

          \"\"<\/p>\n

          TRACERT<\/h3>\n

          Description: Trace route. Shows the IP route to a host, including all the hops between your computer and that host.<\/p>\n

          PowerShell: Test-NetConnection \u2013TraceRoute<\/p>\n

          Sample command lines:<\/p>\n

            \n
          • Test-NetConnection www.google.co.uk \u2013TraceRoute<\/li>\n
          • Test-NetConnection hotmail.com -TraceRoute | Select -ExpandProperty TraceRoute | % { Resolve-DnsName $_ -type PTR -ErrorAction SilentlyContinue }<\/li>\n<\/ul>\n

            \"\"<\/p>\n

            \"\"<\/p>\n

            NETSTAT<\/h3>\n

            Description: Shows current TCP\/IP network connections.<\/p>\n

            PowerShell: Get-NetTCPConnection<\/p>\n

            Sample command lines:<\/p>\n

              \n
            • Get-NetTCPConnection | Group State, RemotePort | Sort Count | FT Count, Name \u2013Autosize<\/li>\n
            • Get-NetTCPConnection | ? State -eq Established | FT \u2013Autosize<\/li>\n
            • Get-NetTCPConnection | ? State -eq Established | ? RemoteAddress -notlike 127* | % { $_; Resolve-DnsName $_.RemoteAddress -type PTR -ErrorAction SilentlyContinue }<\/li>\n<\/ul>\n

              \"\"<\/p>\n<\/li>\n<\/ul>\n

              It is very interesting to know these commands in Powershell.<\/p>\n

              I have tested some range to ping using Powershesll below command sweeps all the range of 192.168.1.0\/24<\/p>\n
