![]() Written by Mike Muuss in 1983, this utility, comprise of about a thousand line of code, was reportedly named "ping" to have it sound like the ping submarine sonar makes. The ping command is one of the primary network troubleshooting tools to test reachability of a remote computer (hence the term "can it be pinged?"). This command uses Internet Control Message Protocol (ICMP) to send out an ECHO_REQUEST to the target computer and waits for an ECHO_REPLY packet. The ping command allows you to send a signal to another computer (either on your local network or a computer on the Internet) to determine if it is active or if it can be reached. Example Ping Result Showing Remote Device Not Responding.ping - Find the IP Address of a Domain Name/Website.ping -a - Find Hostname of an IP Address.ping -n -l - Ping Using Custom Number of Packets and Packet Size.ping - Test Reachability and Latency to a Specific IP.ping - Test Reachability and Latency to a Website.These commands shown here are tested on Windows 10 but most will work in other versions of Windows as well. If you encounter issues accessing a website, sending an email, or opening a file on your network file server, the ping tool is used to test and troubleshoot connectivity issue. If the connections are good and the remote device is online, a good return packet will be received. The device that sent the packet then waits and listens for a return packet. A small data packet is sent through the network to the remote device. Ping uses the Internet Control Message Protocol (ICMP) Echo function as described in RFC 792. Or, it can be a device on the Internet, such as a web server, web site, DNS server, or email server. The device can be another computer, network switch, or a router on your local network. The ping utility is a basic, yet the most widely used network command-line tool used to test network connectivity and name resolution of a remote device.
