The invention provides a method and a system for distributing network addresses of a probe and a central station. The probe carries out the following steps: a configuration judging step, a connecting step, a connection judging step, an address distribution waiting step and a storing step. The method and the system for distributing network addresses of the probe and the central station have the advantageous effects that setting steps after the probe is assembled and produced are reduced; generally speaking, only a piece of fixed information can be configured for a hardware firmware program of the probe, but the fixed information is exactly utilized to identify that the probe is in an initial installation state in the scheme. In the probe assembling and producing process, only the fact that the firmware program writing has no problem needs to be guaranteed, while excessive setting operations are not required.
