Method for forbidding wireless router DHCP to acquire address in college campus network

Abstract

The invention discloses a method for prohibiting a DHCP of a wireless router from acquiring an address in a college campus network, and the method comprises the following steps: employing a DHCP server, which is an initial stage of a session between a DHCP client and the DHCP server; in the second stage of the session, enabling the DHCP server to return a DHCPOffer message to the mobile device, and after an IP address is reserved for a client, enabling the DHCP server to send a DHCPOffer message which comprises the MAC address, the IP address and the lease term of the Client and the IP address of the DHCP server sending the message; in the third stage, enabling the mobile terminal to return a DHCP Request message to the DHCP server, which indicates that the IP address is accepted; in the last stage, enabling the DHCP server to send a DHCP confirmation message which comprises the lease term and other information requested by the mobile terminal. The method is scientific and reasonable in structure and safe and convenient to use, in a traditional mode, automatic address obtaining of the wireless router cannot be controlled, and address obtaining is forbidden through the dhcp server option.

Description

technical field [0001] The invention relates to the technical field of prohibiting a wireless router DHCP from obtaining an address in a college campus network, and specifically relates to a method for prohibiting a wireless router DHCP from obtaining an address in a college campus network. Background technique [0002] The wireless router can be regarded as a repeater, which forwards the broadband network signal connected to the wall of the home to the nearby wireless network equipment through the antenna. It also has some other network management functions, such as dhcp service, nat firewall, mac address filtering, dynamic domain name and other functions; [0003] The phenomenon of privately connecting wireless routers in university campus networks exists and is relatively serious. With the requirements of security audits, once a problem occurs with privately connected wireless routers, it will bring challenges to security audits. Only the corresponding wireless routers ca...

Problems solved by technology

[0004] The present invention provides a method for prohibiting wireless routers from obtaining addresses through DHCP in a college campus network, which can effectively solve the problem of privately connecting wireless routers in college campus networks in the above-mentioned background technology and is relatively serious. Once there is a problem with the wireless router, it will bring challenges to the security audit. It can only locate the corresponding wireless router, and cannot accurately locate the specific personnel; Radio frequency interference is not conducive to the problem of giving full play to the advantages of campus wireless network
