Storage locations, such as voice mailboxes are addressed on a plurality of widely distributed host systems, connect via a network, by defining logical domains Bach of which may include storage locations on more than one host system. The domains are defined by address tables which indicate which host systems provide ranges of address locations. Transfer of data between domains is simplified by the use of translation tables. One type of translation table is an alias table which has entries containing a range in the originating domain, a new domain and a starting point for a range in the new domain, thus defining a one-to-one correspondence between the ranges in the two domains. Another translation table is a gateway table which defines a gateway to a new domain when an input address has characteristics matching a prefix, number of digits, or both, of an entry in the gateway table. Upon finding the closest possible match in the gateway table, the portion of the input address after the prefix, if any, is used as the address in the new domain.
