摘要
In a method and system for preventing IPv6 packet forgery in an Internet Protocol version 6 (IPv6)-Internet Protocol version 4 (IPv4) network of a dual stack transition mechanism (DSTM) environment, a DSTM server receives a request for assignment of an IPv4 address from a DSTM node. The DSTM server determines whether the request is reasonable using a previously stored dynamic address table, assigns the IPv4 address to the DSTM node when the request is reasonable, and updates the dynamic address table to have mapping information of the IPv4 address assigned to the DSTM node. The DSTM server then transmits the assigned IPv4 address to the DSTM node, and transmits the updated dynamic address table to a DSTM border router so as to synchronize its dynamic address table with a dynamic address table of the DSTM border router.
