Abstract: This application provides an address detection method and a related apparatus. The method includes: receiving a first internet protocol (internet protocol, IP) address from a first device, where the first IP address is a to-be-detected IP address of the first device; determining a first information table, where the first information table includes an IP address of one or more devices, and the one or more devices and a first apparatus are at a media access control layer of a same network; determining a second information table based on the first information table; and detecting whether a second IP address that is the same as the first IP address exists in the second information table, where a first media access control address corresponding to the first IP address is different from a second media access control address corresponding to the second IP address. Technical solutions provided in this application can improve accuracy of duplicate address detection.
