Get Your Public IP Using Nginx

Public IP Address

You can always use your own nginx instead of using 3rd party services when you need to know your public IP.

Like this:

# Public IP
location = /ip {
    default_type text/plain;
    return 200 $remote_addr;
}

Or if you need it in JSON format like this:

# Public IP JSON
location = /ip_json {
    default_type application/json;
    return 200 "{\"ip\":\"$remote_addr\"}";
}
