Research on IPv6 Address Security Application based on DUID and SNMP

With the wide application of IPv6, the problem of IPv4 address resource exhaustion has been solved, but it also brings new challenges. Aiming at the address security management problem in IPv6 network, this paper proposes an IPv6 address management and alarm method based on DUID (DHCPv6 Unique Identifier), DHCPv6 and SNMP. In view of the difficulties in IPv6 address management and operation, and the inability to effectively read terminal equipment information in the application scenario of gas mine office network, a management system based on C/S mode was designed. The client collected local equipment network configuration information through the network card, and uploaded it to the server for centralized management. After the server checks the validity, once the illegal access is detected, the system will automatically trigger an alarm and notify the administrator. At the same time, by using SNMP protocol in the server to collect network equipment information, to ensure the effective management of network equipment. The actual deployment and application results show that this method improves the management efficiency in Ipv6 environment, and ensures the convenience and efficiency of IPv6 address management and application security.
