To use curl to test basic network connectivity, you need to know several things: The remote server name or IP address. The protocol for the service to be tested (HTTP, FTP, SMTP, etc.) The port number for the network application you want to test. The curl command on Linux systems is commonly used to download and upload files to or from a remote server. Another interesting thing we can use it for is to determine the public IP address of our system. Ever needed to get your public IP address programmatically? Maybe you're provisioning new cloud servers and need to know your IP - maybe you're behind a corporate firewall and need to tunnel information - whatever the reason: sometimes having a public IP address API is.
