On the internet, each server has a public-facing IP address, which is assigned directly to the server or via a router that sends network traffic to that server.
IP addresses provide an easy way to track the location of the server in the world by using two useful APIs provided by ipinfo.io and ipvigilante.com to get the city, state, and country connected with a server.
Install Curl and jq
To get the IP address geographic location of the server, we need to install curl command line downloader and jq command-line tool to process the JSON data from the geolocation APIs.
$ sudo apt install curl jq #Ubuntu/Debian $ sudo yum install curl jq #CentOS/RHEL $ sudo dnf install curl jq #Fedora 22+ $ sudo zypper install curl jq #openSUSE
Find the Server’s Public IP Address
To get the server’s public IP address, use the following curl command to make an API request to ipinfo.io in your terminal as shown.
$ curl https://ipinfo.io/ip
Get IP Location Data From The API
Once you have got the server public IP address, you can now make a request to ipvigilante.com‘s API to fetch the geolocation data using the following command. Make sure to replace <your ip address> with the server’s public IP.
$ curl https://ipvigilante.com/<your ip address>
Automate API Call using Bash Script
Now to automate the API process, we will create a script called getipgeoloc.sh (you can name it anything you want) using any of your favorite command line editors.
$ vim getipgeoloc.sh
Then copy and paste the following long command in it.
curl -s https://ipvigilante.com/$(curl -s https://ipinfo.io/ip) | jq '.data.latitude, .data.longitude, .data.city_name, .data.country_name'
Save the file and make the script executable with the following command.
$ chmod +x getipgeoloc.sh
Finally, run the script to get your Linux IP geographical location.
The above script shows the city and country name along with the approximate latitude and longitude coordinates.
Alternatively, you can also run the above command without saving it in a script as shown.
$ curl -s https://ipvigilante.com/$(curl -s https://ipinfo.io/ip) | jq '.data.latitude, .data.longitude, .data.city_name, .data.country_name'
