For example, the server may return a different destination address at different times or in response to translation requests from different terminals. The server also can query a primary destination terminal device, and condition the response to the calling terminal on the status of the primary terminal. For example, if the primary terminal is `live` the server forwards the address of that termina

For example, the server may return a different destination address at different times or in response to translation requests from different terminals. The server also can query a primary destination terminal device, and condition the response to the calling terminal on the status of the primary terminal. For example, if the primary terminal is `live` the server forwards the address of that terminal to the calling terminal device to set up communications. Otherwise, the server returns alternate destination address information. The server also supports a wide variety of different types of translations, including domain name to address, domain name to telephone number, and telephone number to address. What is claimed is: 1. A server, comprising: an interface for coupling the server to a system of interlinked packet data networks using packet addresses defined in a first protocol; a central processing unit coupled to the interface; a data storage system accessible by the central processing unit; and software running on the central processing unit for processing a query for translation of a name specified in a second protocol received via the interface to generate a reply message for transmission via the interface, wherein: the software controls the central processing unit to include an address conforming to the first protocol and relating to a first destination in the reply message if parameters relating to the query satisfy a first criteria defined in a routing control record stored in the data storage system, and the software controls the central processing unit to include information relating to a second destination in the reply message if parameters relating to the query satisfy a second criteria defined in the routing control record. 2. A server as in claim 1, wherein the first and second criteria relate to time windows. 3. A server as in claim 1, wherein the first and second criteria relate to status of a predetermined destination terminal device. 4. A server as in claim 1, wherein the data storage system stores at least one translation table and a plurality of conditional analysis routing control records. 5. A server as in claim 1, wherein the wherein the information relating to the second destination comprises an address of the second destination conforming to the first protocol. 6. A server as in claim 1, wherein the wherein the information relating to the second destination comprises a telephone number. 7. A domain name server, comprising: an interface for coupling the domain name server to a system of interlinked networks using Internet Protocol (IP) addresses; a central processing unit coupled to the interface; a data storage system accessible by the central processing unit; and software running on the central processing unit for processing a translation query received via the interface to generate a reply message for transmission via the interface, wherein: the software controls the central processing unit to include an IP address used to communicate with a first destination in the reply message if parameters relating to the query satisfy a first criteria defined in a routing control record stored in the data storage system, and the software controls the central processing unit to include routing information relating to a second destination in the reply message if parameters relating to the query satisfy a second criteria defined in the routing control record. 8. A domain name server as in claim 7, wherein the first and second criteria relate to time windows. 9. A domain name server as in claim 7, wherein the first and second criteria relate to status of a predetermined destination terminal device. 10. A domain name server as in claim 7, wherein the data storage system stores at least one translation table and a plurality of conditional analysis routing control records. 11. A server, comprising: an interface for coupling the server to a system of interlinked packet data networks using packet addresses defined in a first protocol; a central processing unit coupled to the interface; a data storage system accessible by the central processing unit; and software running on the central processing unit, causing the server to respond to a query for translation of a name specified in a second protocol received via the interface by transmitting a status query via the interface to a destination terminal device associated with the name, wherein the software controls the central processing unit to include an address of the destination terminal device conforming to the first protocol in a reply to the query for translation only if the server receives a predetermined reply to the status query from the destination terminal. 12. A server as in claim 11, wherein the data storage system stores at least one translation table and a plurality of conditional analysis routing control records. 13. A domain name server, comprising: an interface for coupling the domain name server to a system of interlinked networks using the Internet Protocol (IP) addresses; a central processing unit coupled to the interface; a data storage system accessible by the central processing unit; and software running on the central processing unit, causing the domain name server to respond to a query for translation of a name specified in a second protocol received via the interface by transmitting a status query via the interface to a destination terminal device associated with the name, wherein the software controls the central processing unit to include an IP address of the destination terminal device in a reply to the query for translation only if the central processing unit receives a predetermined reply to the status query from the destination terminal. 14. A domain name server as in claim 13, wherein the data storage system stores at least one translation table and a plurality of conditional analysis routing control records. receiving a name translation request at a server coupled to a public packet data network; executing a conditional analysis in response to the name translation request; if the conditional analysis produces a first result, translating a name included in the name translation request into a first destination address; if the conditional analysis produces a second result, translating the name included in the name translation request into a second destination address; and transmitting a response message containing the first or the second destination address to a calling device for use in establishing communication at least partially through the public packet data network. 16. A method as in claim 15, wherein the name is a textual domain name comprising a plurality of words. 17. A method as in claim 15, wherein the name comprises a telephone number. 18.

A method as in claim 15, wherein the calling device is a terminal device. 22. A method as in claim 21; wherein the terminal device is a computer having two-way audio communication capabilities. 23. A method as in claim 15, wherein the calling device is a telephone gateway coupled between the public packet data network and a switched telephone network. 24. A method comprising: receiving a name translation request at a server coupled to a public packet data network; transmitting a status query from the server through the public packet data network to a terminal device associated with a name included in the name translation request; and if the terminal device provides a predetermined answer to the status query, formulating and transmitting a reply to the name translation request, said reply containing address information associated with the terminal device. 25. A method as in claim 24, wherein the address information comprises a telephone number. 26. A method as in claim 24, wherein the address information comprises an address of the public packet data network. 27. A method as in claim 26, wherein the address of the public packet data network comprises an Internet Protocol (IP) address. 28.
