Abstract
The present invention is to provide a method applied to at least a network device connected to a network and enabling the network device to send a request for an Internet Protocol address (IP address) to a DHCP server connected with the network according to the Dynamic Host Configuration Protocol (DHCP) and, in the meantime, automatically generate an IP address according to the automatic link-local IP address allocation protocol. When an IP address is first acquired according to either the DHCP or the automatic link-local IP address allocation protocol, the network device exchanges data with other network device of the same segment by using said IP address first acquired, and constantly trying to acquire another IP address according to either the DHCP or the automatic link-local IP address allocation protocol, so as to effectively reduce the time for acquiring an IP address needed by a conventional network device.
