Send UDP messages to a destination IP address and port number, listen for incoming UDP messages on a user-defined port, and echo received messages back to the source. Combine the sender and receiver into a single "UDP ping" application to test the communication channel between two network hosts, and illustrate the notifier method to stop

An adversary sends a UDP datagram to the remote host to determine if the host is alive. If a UDP datagram is sent to an open UDP port there is very often no response, so a typical strategy for using a UDP ping is to send the datagram to a random high port on the target.

Nmap “ping sweep” is a method to discover connected devices in a network using the nmap security scanner, for a device to be discovered we only need it to be turned on and connected to the network. ping packets is a type of ICMP packets.Is there any relation between ICMP with TCP.In other can we guaranty their arrival in the network I want to know ICMP packets in the network is tcp or udp or Specifying the "udp" protocol causes the ping() method to send a udp packet to the remote host's echo port.
