Abstract

An e-mail message or other communication received over a computer network is processed so as to be directed to a user-designated host server. An Internet service provider or other organization assigns host names to a particular user for each network service provided to that user. Each of the host names specifies a user, a service, e.g., e-mail, homepage and network telephony, and a domain name of the assigning organization. A mapping stored for each host name correlates the host name with an Internet Protocol (IP) address of the user-designated host server for the corresponding service. When an address request for an incoming communication directed to a particular user arrives in a Domain Name System (DNS) server associated with the organization domain, the stored mapping for the corresponding user and service is processed to obtain the appropriate IP address. This address is returned to the requesting DNS server associated with a domain of the sender, and is used to establish a connection between the sender domain and the user-designated host server for delivering the communication. The user-designated host server may be a personal computer associated with the user.

Claims

1. A method of processing a communication received over a computer network, the method comprising the steps of:

storing for a given user of the network a mapping between a host name and an address of a user-designated host server for hosting a particular network service provided to that user, wherein the user is one of a plurality of users associated with an organization, and the host name specifies the user and the particular network service; and

directing an incoming communication of the network service addressed to the user to the host server specified in the mapping.

2. The method of claim 1 wherein the organization is an Internet service provider.

3. The method of claim 1 wherein the network service includes at least one of an e-mail service, a homepage service, and a network telephony service.

4. The method of claim 1 wherein the user-designated host server is a personal computer associated with the user.

5. The method of claim 1 further including the step of storing information that is used to limit the application of the directing step to incoming communications.

6. The method of claim 5 wherein the information includes a user-designated time period for which an incoming communication received during that time period should be directed to the host server specified in the mapping.

7. The method of claim 1 wherein the storing step further includes storing for the given user of the network a plurality of mappings, with each mapping specifying a host name and an address of a user-designated host server for hosting a particular network service provided to that user, and the directing step further includes directing an incoming communication of the network service addressed to the user to a host server specified in a particular one of the plurality of mappings, wherein the particular one of the mappings selected for use upon receipt of the incoming communication is determined in accordance with at least one user-designated constraint.

8. The method of claim 1 wherein the step of storing a mapping further includes the step of storing the mapping in a record of a Domain Name Service (DNS) server associated with a domain of the user.

9. The method of claim 1 wherein the step of storing a mapping further includes the step of storing the mapping in a non-DNS server associated with a domain of the user, wherein the mapping is supplied from the non-DNS server to a DNS server associated with a domain of the user upon receipt of an address request in the DNS server.

10. The method of claim 1 further including the steps of:

returning a record including an address of the user-designated host server from a DNS server associated with the domain of the user to a requesting DNS server in another domain; and

designating the record as non-cacheable.

11. An apparatus for processing a communication received over a computer network, the apparatus comprising:

a memory for storing for a given user of the network a mapping between a host name and an address of a user-designated host server for hosting a particular network service provided to that user, wherein the user is one of a plurality of users associated with an organization, and the host name specifies the user and the particular network service; and

at least one additional server operative to determine, upon receipt of an incoming communication of the network service addressed to the user, an address of the host server specified in the mapping.

12. The apparatus of claim 11 wherein the organization is an Internet service provider.

13. The apparatus of claim 11 wherein the network service includes at least one of an e-mail service, a homepage service, and a network telephony service.

14. The apparatus of claim 11 wherein the user-designated host server is a personal computer associated with the user.

15. The apparatus of claim 11 wherein the memory further stores information specifying at least one constraint relating to direction of incoming communications to the user-designated host server.

16. The apparatus of claim 15 wherein the constraint includes a user-designated time period for which an incoming communication received during that time period should be directed to the host server specified in the mapping.

17. The apparatus of claim 11 wherein the memory stores for the given user of the network a plurality of mappings, with each mapping specifying a host name and an address of a user-designated host server for hosting a particular network service provided to that user, and wherein the at least one additional server is further operative to direct an incoming communication of the network service addressed to the user to a host server specified in a particular one of the plurality of mappings, and further wherein the particular one of the mappings selected for use upon receipt of the incoming communication is determined in accordance with at least one user-designated constraint.

18. The apparatus of claim 11 wherein the at least one additional server is a Domain Name Service (DNS) server associated with a domain of the user.

19. The apparatus of claim 11 wherein the at least one additional server includes a DNS server and a non-DNS server, both associated with a domain of the user, and wherein the mapping is supplied from the non-DNS server to the DNS server upon receipt of an address request in the DNS server.

20. The apparatus of claim 11 wherein the at least one server is a DNS server associated with a domain of the user, and the DNS server is operative to return a record including an address of the user-designated host server to a requesting DNS server in another domain, and to designate the record as non-cacheable.

21. An apparatus for processing a communication received over a computer network, the apparatus comprising:

means for storing for a given user of the network a mapping between a host name and an address of a user-designated host server for hosting a particular network service provided to that user, wherein the user is one of a plurality of users associated with an organization, and the host name specifies the user and the particular network service; and

means for directing an incoming communication of the network service addressed to the user to the host server specified in the mapping.
