The embodiments of the present invention disclose a private network address allocation method, comprising: receiving from a terminal a Dynamic Host Configuration Protocol (DHCP) request for a private network address allocation; acquiring from an address allocation network element a private network address according to the DHCP request, and continuing to acquire a private network address from the address allocation network element when the acquired private network address conflicts with any stored private network address; when the private network address acquired from the address allocation network element does not conflict with any stored private network address, returning a DHCP response message to the terminal, the DHCP response message carrying the acquired private network address. The embodiments of the present invention also disclose a private network address allocation method, device, and system. The present invention ensures that the private network address returned to the terminal does not conflict with the private network addresses of other terminals, thereby ensuring the terminal can conduct normal network communications. |
