Abstract
Disclosed are a system and data card for stateless automatic configuration of an IPv6 address and the method for implementing the same, and the method includes: an IPv6 address configuration way of a data card is set and stored according to an IPv6 address allocation strategy of a current network, after successful establishment of an IPv6 dialup connection and reception of a router advertisement request message transmitted by a terminal for acquiring a prefix address, the data card determines the set IPv6 address allocation way, and when the set IPv6 address allocation way is a static configuration way, a router advertisement response message is discarded and a valid IPv6 global unicast address is reported to the terminal. By means of the system, data card and method, it is possible to solve a problem that data transmission can not be normally performed by an existing data card implementing dialup in an Ethernet link way when interface identifiers are allocated by a network.
