Abstract
A method for selecting a gateway node for a terminal which connects to its registered domain via an access domain and, in a predetermined scenario, an intermediate domain, the access domain having an associated domain name system arranged to return an address of a gateway node based on a domain name system query. The method includes using a first part of such a query to identify the registered domain of the terminal to the domain name system and a second part of the query to indicate to the domain name system that it should use a predetermined mapping to return the address of a gateway node based on the query, the predetermined mapping being one which returns an address of a gateway node either in the registered domain or in an intermediate domain based on the registered domain identified in the query and on the access domain.
