Abstract
The embodiment of the invention discloses a method for allocating IP addresses. The method comprises the following steps that: a DHCP server receives a DHCP request sent by a digital TV receiving terminal, wherein the DHCP request comprises OPTION82 information; and the DHCP server judges whether the OPTION82 information in the DHCP request is a preset OPTION82 value or not, if so, allocates an intranet IP address to the digital TV receiving terminal according to the DHCP request, and otherwise, allocates an extranet IP address to the digital TV receiving terminal. The method and the device have the advantages of effectively combining a DHCP and option82, overcoming the safety defects existing in the conventional enterprise networks and simultaneously further effectively managing the IP to really realize the dual functions of network safety and network management.
Description
Technical field
The present invention relates to logical neighborhood, relate in particular to a kind of IP address assignment method, Apparatus and system.
Background technology
DHCP (Dynamic Host Configuration Protocol, dynamic host allocation protocol) allows server to client dynamic assignment IP (Internet Protocol, the agreement that interconnects between the network) address and configuration information.DHCP makes the network manager can manage a network system concentratedly, and the IP address in the network is distributed automatically., DHCP is divided into two parts: one is server end, and another is a client.All IP network setting datas are all by the Dynamic Host Configuration Protocol server centralized management, and the responsible DHCP requirement of handling client; Client then can be used the IP world data of getting off from server-assignment.
Option82 is an agreement among the DHCP, it has expanded the DHCP function, making DHCP differentiate DHCP request by two parameters is which DHCP from which switch sends, that is to say, it makes DHCP support many vlan (Virtual Local Area Network, VLAN).
In the prior art, DHCP and option82 and not yet in effect the combination can't be eliminated the safety defect that traditional forms of enterprises's net exists, and the while also is unrealized to effective management of the IP of network.
