Abstract

Methods, systems, and products are disclosed for user defined preferred DNS routing that include mapping for a user in a data communications application a domain name of a network host to a network address for a preferred DNS server, wherein the preferred DNS server has a network address for the domain name; receiving from the user a request for access to a resource accessible through the network host; and routing to the preferred DNS server a DNS request for the network address of the network host, the DNS request including the domain name of the network host. In typical embodiments, mapping a domain name to a network address for a preferred DNS server is carried out by storing, through the data communication application, the domain name in association with the network address for a preferred DNS server in a data structure in computer memory.

Claims

1. A method of user defined preferred DNS routing, the method comprising:

mapping for a user in a data communications application a domain name of a network host to a DNS network address for a preferred DNS server, wherein the preferred DNS server has a host network address for the domain name, and wherein mapping the domain name to the DNS network address for the preferred DNS server further comprises receiving from a user the domain name for the network host having the domain name registered on the preferred DNS server and receiving from the user the DNS network address for the preferred DNS server;

receiving from the user a request for access to a resource accessible through the network host; and

routing to the preferred DNS server a DNS request for the host network address of the network host, the DNS request including the domain name of the network host.

2. The method of claim 1 wherein mapping a domain name to a DNS network address for a preferred DNS server further comprises associating, through the data communication application, an identifier for the user with the domain name and with the DNS network address for a preferred DNS server in a table in computer memory, the table capable of supporting many-to-many relationships between user identifiers, domain names, and DNS network addresses for preferred DNS servers.

3. The method of claim 1 wherein routing a DNS request for the host network address of the network host is carried out by the data communications application.

4. The method of claim 1 wherein routing a DNS request for the host network address of the network host is carried out by an operating system.

5. The method of claim 1 wherein routing a DNS request for the host network address of the network host is carried out by a predesignated DNS server, wherein a predesignated DNS server is a standard DNS server having a network address that is predesignated as a default operating parameter for the data communications application.

6. The method of claim 1 further comprising:

receiving from the preferred DNS server a DNS response identifying the host network address of the network host; and

accessing the resource through the host network address of the network host.

7. A system for user defined preferred DNS routing, the system comprising:

means for mapping for a user in a data communications application a domain name of a network host to a DNS network address for a preferred DNS server, wherein the preferred DNS server has a host network address for the domain name, and wherein means for mapping the domain name to the DNS network address for the preferred DNS server further comprises means for receiving from a user the domain name for the network host having the domain name registered on the preferred DNS server and means for receiving from the user the DNS network address for the preferred DNS server;

means for receiving from the user a request for access to a resource accessible through the network host; and

means for routing to the preferred DNS server a DNS request for the host network address of the network host, the DNS request including the domain name of the network host.

8. The system of claim 7 wherein means for mapping a domain name to a DNS network address for a preferred DNS server further comprises means for associating, through the data communication application, an identifier for the user with the domain name and with the DNS network address for a preferred DNS server in a table in computer memory, the table capable of supporting many-to-many relationships between user identifiers, domain names, and DNS network addresses for preferred DNS servers.

9. The system of claim 7 wherein means for routing a DNS request for the host network address of the network host further comprises the data communications application.

10. The system of claim 7 wherein means for routing a DNS request for the host network address of the network host further comprises an operating system.

11. The system of claim 7 wherein means for routing a DNS request for the host network address of the network host further comprises a predesignated DNS server, wherein a predesignated DNS server is a standard DNS server having a network address that is predesignated as a default operating parameter for the data communications application.

12. The system of claim 7 further comprising:

means for receiving from the preferred DNS server a DNS response identifying the host network address of the network host; and

means for accessing the resource through the host network address of the network host.

13. A computer program product for user defined preferred DNS routing, the computer program product comprising:

recording medium;

means, recorded on the recording medium, for mapping for a user in a data communications application a domain name of a network host to a DNS network address for a preferred DNS server, wherein the preferred DNS server has a host network address for the domain name, and wherein means, recorded on the recording medium, for mapping the domain name to the DNS network address for the preferred DNS server further comprises means, recorded on the recording medium, for receiving from a user the domain name for the network host having the domain name registered on the preferred DNS server and means, recorded on the recording medium, for receiving from the user the DNS network address for the preferred DNS server;

means, recorded on the recording medium, for receiving from the user a request for access to a resource accessible through the network host; and

means, recorded on the recording medium, for routing to the preferred DNS server a DNS request for the host network address of the network host, the DNS request including the domain name of the network host.

14. The computer program product of claim 13 wherein means, recorded on the recording medium, mapping a domain name to a DNS network address for a preferred DNS server further comprises means, recorded on the recording medium, for associating, through the data communication application, an identifier for the user with the domain name and with the DNS network address for a preferred DNS server in a table in computer memory, the table capable of supporting many-to-many relationships between user identifiers, domain names, and DNS network addresses for preferred DNS servers.

15. The computer program product of claim 13 wherein means, recorded on the recording medium, for routing a DNS request for the host network address of the network host further comprises the data communications application.

16. The computer program product of claim 13 further comprising:

means, recorded on the recording medium, for receiving from the preferred DNS server a DNS response identifying the host network address of the network host; and

means, recorded on the recording medium, for accessing the resource through the host network address of the network host.
