Example Embodiment

[0046] Example one

[0047] Based on the above content, this embodiment first provides a method for discovering network devices, such as figure 1 As shown, including the following steps:

[0048] Step S100, enumerate the IP address of the device to be scanned in the target network.

[0049] The target network refers to a network system with a local computer equipment group such as an Ethernet or a local area network. The enumerated network generally refers to the local network segment under the large network system. The IP address range of the device to be scanned can be determined according to the IP address of the detection device, and the IP address is generally the IP address of all devices in the local network segment except the detection device address, broadcast address, and gateway address. For example, if the IP of the detection device (generally called the local machine) is 192.168.1.100, the mask is 255.255.255.0, and the gateway is 192.168.1.1, the enumerated range is f...

Example Embodiment

[0065] Example two

[0066] Different from the first embodiment, this embodiment provides a method for discovering network devices, such as figure 2 As shown, in addition to the steps S100 to S103, it also includes the steps:

[0067] Step S200, read the MAC list.

[0068] The MAC list may be a historical list read from a system server, and its purpose is to compare it with the current MAC list obtained by performing steps S100 to S103 to obtain the MAC of a newly added device in the current network device. Address, and focus on the detection of the above-mentioned new equipment.

[0069] In other embodiments, the MAC list may also be the current MAC list, and reading the MAC list can provide the system with more sufficient device location resources for subsequent application development.

[0070] This step can be executed after step S100 to step S103 are executed, or it can be performed based on previous historical MAC list data. This embodiment does not limit the sequence between th...

Example Embodiment

[0071] Example three

[0072] Different from the first embodiment, this embodiment provides a method for discovering network devices, such as image 3 As shown, in addition to the steps S100 to S103, it also includes the steps:

[0073] Step S300, clear the ARP cache of the detection device.

[0074] The step S300 is performed before enumerating all IP addresses to be scanned in the target network.

[0075] The goal of step S300 is to clear the ARP cache of the historical detection device to re-perform the ARP detection of all devices in the system to improve the detection accuracy.

Abstract

The invention provides a method, device and system for discovering network equipment. The method comprises the steps of: enumerating equipment IP addresses to be scanned in a target network; broadcasting one target address as a first ARP request message of the equipment IP addresses to be scanned; when the scanned IP addresses exist in an ARP cache of detection equipment, storing the IP addresses and corresponding MAC addresses; and after scanning on all the IP addresses to be scanned in the target network is completed, reporting the stored IP addresses and the MAC addresses thereof to a server. According to the method, device and system provided by the invention, detection efficiency of equipment detection can be improved.

Description

technical field [0001] The technical solution of the present invention relates to the field of computer technology, and in particular to a method for discovering network equipment, a device for discovering network equipment, and a system for discovering network equipment. Background technique [0002] The rapid development of information technology has vigorously promoted the wide application of computer networks and information systems in governments, enterprises and institutions, and provided a solid guarantee for the electronization, automation and informatization of office and production construction. The network environment in the government intranet (public security, procuratorate, court, government, finance and taxation, electric power, etc.) is huge and complex. How to quickly and accurately detect and discover illegally connected devices in the network has become an important task for national security and confidentiality. The most important. [0003] The most impo...
