答案 (The Answer)
SuperUser contributors AlikElzin-kilaka and Ben N have the answer for us. First up, AlikElzin-kilaka:
超级用户贡献者AlikElzin-kilaka和Ben N为我们找到了答案。 首先，AlikElzin-kilaka：
There is a service (IPInfo) that can provide the results. You can invoke it using curl, for example:
有一个可以提供结果的服务( IPInfo )。 您可以使用curl调用它，例如：
- curl ipinfo.io 卷曲ipinfo.io
Result:
结果：
A specific IP’s info can also be requested:
还可以请求特定IP的信息：
- curl ipinfo.io/216.58.194.46 卷曲ipinfo.io/216.58.194.46
Result:
结果：

Followed by the answer from Ben N:
随后是Ben N的回答：
Since the question does not specify an operating system, this is how to get that same information with PowerShell’s curl (actually an alias of Invoke-WebRequest):
由于该问题未指定操作系统，因此这是如何通过PowerShell的curl(实际上是Invoke-WebRequest的别名)获取相同的信息：
- (curl ipinfo.io).Content (curl ipinfo.io)。内容
Which produces a JSON string. To get the object that the JSON represents, use ConvertFrom-Json:
产生一个JSON字符串。 要获取JSON表示的对象，请使用ConvertFrom-Json ：
- curl ipinfo.io | ConvertFrom-Json curl ipinfo.io | ConvertFrom-Json
Since that is a PowerShell object, you can easily get specific fields from it. For example, this command gets just the external IP address as a string:
由于这是一个PowerShell对象，因此您可以轻松地从中获取特定字段。 例如，以下命令仅将外部IP地址作为字符串获取：
- (curl ipinfo.io | ConvertFrom-Json).ip (curl ipinfo.io | ConvertFrom-Json).ip
Note that the geographical information from this service is not super accurate, but it did locate me within 20 miles or so of my actual location and the ISP information seems to be reliable.
请注意，此服务提供的地理信息不是非常准确，但是它确实将我定位在距我实际位置约20英里的范围内，并且ISP信息似乎是可靠的。
