The Internet Control Message Protocol is used to send error and status messages and requests. The ICMP module implements the Echo Reply message type (commonly referred to as a ping) which can be used to determine if a specified host is reachable across an IP network from a device running the TCP/IP stack. An ICMP server is also supported to respond to pings from other devices.
