There are many occasions when it is useful to obtain our IP address from the command line or to obtain information about a specific IP from a script. In this mini-howto we will use the service offered by ipinfo.io.
To use the service, it is as simple as making a web request using curl:
curl ipinfo.io
On the other hand, if we want to request information about a specific IP:
curl ipinfo.io/8.8.8.8
{
"ip": "8.8.8.8",
"hostname": "google-public-dns-a.google.com",
"city": "Mountain View",
"region": "California",
"country": "US",
"loc": "37.3860,-122.0840",
"org": "AS15169 Google Inc.",
"postal": "94035",
"phone": "650"
}
