Embodiment Construction
[0043] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments It is a part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.
[0044] The distribution area of the local area network is limited, and it can be large or small, as large as the connection between a building and adjacent buildings, as small as the connection between offices. Compared with other networks, the LAN itself has faster transmission speed, more stable performance, simple framework, and is closed. Searc...

The invention provides an equipment searching method and device, equipment and a storage medium, and is applied to the fields of communication technology, information processing technology and the like. In the technical scheme, the IP address of first equipment is a first IP address, the first equipment generates a request message according to the first IP address, the request message carries protocol information, the first IP address and a second IP address, the second IP address is the IP address of second equipment, and the first IP address and the second IP address are located in the same network segment. The protocol information is used for indicating searched equipment which performs point-to-point data communication with the first equipment; sending the request message to the second equipment; and receiving a response message, sending the response message by the second equipment when the second equipment determines that the second equipment belongs to the searched equipment according to the protocol information, and the response message carries the IP address of the searched equipment. The function of searching and finding the equipment is realized in a unicast mode, and the search failure rate can be reduced.
Description
technical field [0001] The present application relates to the technical field of communications, and in particular to a device search method, device, device and storage medium. Background technique [0002] A local area network is a regional network formed in a local area. Devices under the same local area network can realize point-to-point data communication, but the Internet Protocol (Internet Protocol, IP) address of the other party needs to be known before data communication. [0003] At present, the commonly used ways to obtain the IP address of the other party include broadcast search and multicast search. Specifically, the message carrying protocol information sent by the search initiator is forwarded to all devices in the local area network (broadcast search) or devices in the same IP address segment (multicast search) through the network connection device; The device analyzes the message to obtain the protocol information, and the device that conforms to the proto...
