摘要

The present invention relates to a method for checking and searching a host operation condition in a network using packets generated in the network and comprises a host information packet capture step for capturing the corresponding packet to host information generated in the network using an agent; and a host information acquisition step for acquiring the host information using Ethernet source MAC information, Ethernet destination MAC information, IPv6 source IP information, IPv6 destination IP information, ICMPv6 target address information, or ICMPv6 link-layer address information in the corresponding packet to the host information captured using the agent.
