Làm thế nào để bạn tìm vị trí địa lý của máy tính bằng cách sử dụng dòng lệnh?

How do I find a computer’s internet (IP address) location using the command line? Would I use curl or wget, for example?

There is a service (IPInfo) that can provide the results. You can invoke it using curl, for example:

curl ipinfo.io

Result:

curl ipinfo.io/216.58.194.46

Result:

Source: How to look up the geographic location of an IP address from the command line

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):

(curl ipinfo.io).Content

Which produces a JSON string. To get the object that the JSON represents, use 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:

(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.
