During a ping sweep in which all network devices are tested, healthy devices should respond within a narrow time frame. Each of these inputs can potentially produce different information, which could inform diagnostics and general IP address management strategies.Ī user might identify an issue flagged by an echo response via the time output field. An IP address input will result in a direct round-trip time result (RTT). A domain name input, on the other hand, will first access the domain’s web server. If you input a hostname for a device on a network, for instance, the ping route will be directed to the local DNS server so it can acquire the relevant IP address. The input determines the route taken by the echo request, with the potential to expose any delays or issues with the route, so steps can be taken to fix them. When the echo request is sent, the input value can either be a host, a domain name, or an IP address. The echo response then replies, and the nature of the reply can reveal important information about the IP address range the ping was sent to. Essentially, an echo request is the packet of data sent to either a specific IP address or a range of IP addresses. These hosts are typically computers, but anything can be a host, including printers, computer systems, websites, networks, and devices.Įcho request and echo response are the two fundamental aspects of how ping functions.
