Recognizing an installation position of a network device according to an internet protocol (IP) address through a network device installation position table and an IP address assigning table

摘要

An IP address assigning method is provided. Firstly, an IP address request packet containing a media access control address is transmitted to a DHCP server. The IP address request packet is analyzed, so that the media access control address is acquired. Then, at least one address forwarding table of at least one network switch is acquired. Then, the address forwarding table is analyzed according to the media access control address, so that an assigned number of a port of the network switch is acquired. Then, a predetermined IP address listed in an IP address assigning table is assigned to the network device according to the assigned number of the port of the network switch. Afterwards, the media access control address and/or the assigned IP address is recorded in a field of the IP address assigning table corresponding to the assigned number of the port of the network switch.

1. An internet protocol (IP) address assigning method, comprising steps of:
(a) issuing an IP address request packet containing a media access control address from at least one network device, and transmitting said IP address request packet to a dynamic host configuration protocol (DHCP) server through at least one network switch; (b) analyzing said IP address request packet by said DHCP server, so that said media access control address is acquired; (c) acquiring at least one address forwarding table of said at least one network switch by said DHCP server; (d) analyzing said at least one address forwarding table by said DHCP server according to said media access control address, thereby acquiring an assigned number of a port of said network switch which is electrically connected with said network device; (e) assigning an available IP address to said network device by said DHCP server, or assigning a predetermined IP address listed in an IP address assigning table to said network device according to said assigned number of said port of said network switch which is electrically connected with said network device; and (f) recording said media access control address and/or said assigned IP address in a field of said IP address assigning table corresponding to said assigned number of said port of said network switch by said DHCP server after the IP address is assigned, wherein an installation position of said network device is recognized according to said IP address through a network device installation position table and said IP address assigning table, and the installation position of said network device represents a detailed position of said network device in a data center which comprises a receiving space, a rack, and a layered building space; wherein said network device is installed at the installation position by referring to said network device installation position table.
