A ping sends a request to the site typed in and brings it back to your computer, giving you the total time it took for the trip. Times on the Internet can range from 80ms (milliseconds) to 250ms, which is considered normal during peak hours. A ping is a great tool for finding out the current status of your domain. By pinging your domain, you can tell if the IP number it returns matches the IP number you believe your site to be on.
