It’s useful for identifying active devices on your network, ensuring devices are functioning correctly and crucially detecting unrecognized devices which may be nefarious and require further investigation.Ī ping involves a packet of data being sent to a specific IP address (known as an echo request), if the device is active and healthy it will respond (known as an echo reply) and likely provide additional information that might help diagnose any network issues.Ī ping sweep (also known as an ICMP sweep) follows the same process but involves sending multiple requests to multiple addresses at one time. A ping sweep is a simple network scanning technique that returns a range of active and inactive IP addresses on your network.
