#Script to retrieve network details using ipconfig

<# This function takes variable as a parameter and returns a string.
Desc: "ipconfig"" command returns string as a result.
like for IPv6, "Link-local IPv6 Address . . . . . : fe80::18fd:e072:774e:6799%11".
we are replacing the first colon ":"  to "," (in order to avoid conflicts with
other colon used in the value i.e fe80::18fd:e072:774e:6799%11 )
so that we can group rest of the string as a result after comma "," #>

    $result = $replacedStr.ToString().Split(',')[1]
