Abstract
The present invention relates to an addressing method and system for using an anycast address, wherein a data source or server (21 to 23) can be registered in a network device to become a possible receiver for anycast traffic for a specific anycast address. This is achieved by providing a mapping and binding update function of the anycast address to the server's real address. The anycast server can provide authentication data to the client providing a proof that the server indeed has been authorized to respond to the used anycast address. Thereby, an anycast address can be used as a source address and an authorization of anycast servers can be provided.
