The invention discloses a method and equipment for releasing IP addresses by a DHCP server. In the method, a wireless access point acquires IP addresses of user terminals by monitoring the process of acquiring the IP addresses from the DHCP server by the user terminals; the wireless access point detects the data flow of the user terminals, and when the wireless access point discovers that one user terminal does not have data flow continuously in the preset time, the wireless access point sends the DHCP Release message of the user terminal to the DHCP server to notify the DHCP server to release the IP address occupied by the user terminal; and the DHCP server receives the DHCP Release message sent from the wireless access point and releases the IP address which is idle at the user terminal and is carried in the message. In the invention, when the user terminal stops using the IP address, the DHCP server is notified in time to release the IP address allocated to the user terminal.
