Hello all,\n\nI have one technical question that I don't know to solve,\nplease advise:\n\nScenario:\nWe send ICMP echo packets to a targeted computer and to\nreceive the ICMP echo reply packet if the targeted\ncomputer is online. This can be done by using PING\ncommand. After issuing the PING command, we can issue the\nARP command to check the Ethernet address that has been\ncached in our computer, thus establishing the IP address\nto Ethernet Address correspondence. But this approach can\nonly handle single computer. For multiple computers, we\nwill have to do it one by one and the process will be\nslow to scan ALL the computer in the LAN segment near us.\n\nWe want a efficient solution for the above scenario, can\nyou suggest one?\n\nAre there any tools available?\n\nPleae help. Thanks a lot.
