Method for high effectively searching network equipment address in network

Abstract

This invention provides a method for quickly seeking for network device addresses including 1) carrying out Traceroute operation to get the gate address of the sought address, 2) acquiring the corresponding MAC address of the sought address according to the gate address, 3) acquiring address list of all exchanges in its corresponding subnets, 4)initiating the multithread to seek for the acquired MAC address in step (2) from the list and outputting the result.

Description

field of invention [0001] The invention relates to network security technology, in particular to a method for rapidly searching the IP address (network layer address) and MAC address (link layer address) of equipment in the network. Background technique [0002] In a computer network, each communication device (such as router, switch, etc.) and user equipment (such as server, personal computer, printer, etc.) has an identifier, which is used to uniquely represent the node. In a TCP / IP (Transmission Control Protocol / Internet Protocol) network, an IP address or a MAC address is used to identify a communication device and a user device. Generally, user equipment has an IP address and a MAC address, and communication equipment has a MAC address, with or without an IP address. A TCP / IP network can be divided into subnets based on IP address ranges. Data forwarding between multiple subnets is performed by at least one router or a communication device with a router forwarding fun...

AI Technical Summary

Problems solved by technology

[0017] 1. High requirements for administrators, heavy search work, long search cycle and low efficiency;

[0018] 2. Since the information in the forwarding table changes dynamically, it is likely that it cannot be found in a predetermined search, and the probability of success is not high;

[0019] 3. Due to the long search cycle, the information may have disappeared in the communication device before the location is not located, making it difficult to locate illegal users

[0020] 4. In a large-scale network, area-based maintenance is generally implemented, and each administrator is only responsible for the telnet password of some devices. Therefore, if the gateway and other devices are not in the charge of the administrator, this solution cannot be implemented

[0021] Due to the above reasons, in a large network, the address lookup method of the prior art cannot be implemented basically
