What are hostnames of websites?

They are part of the URL (Uniform Resource Locator) structure and typically consist of two or more components separated by periods (dots). Here's an example of a typical website hostname: "www.google.com" In this example, "www" is a commonly used subdomain prefix that stands for "World Wide Web," "google" is the second-level domain (SLD), and ".com" is the top-level domain (TLD). Collectively, they form the hostname that uniquely identifies the website.

Can I ping a hostname?

Yes, you can ping a hostname. The ping command is a commonly used network utility that allows you to check the connectivity and measure the round-trip time (RTT) between your computer and a remote host, which can be specified by either an IP address or a hostname.
