Abstract

An exemplary method includes booting a computing device, in response to the booting, accessing a file that includes domain names and resolving at least one of the domain names by issuing a request to a server where the resolving occurs as a background process. An exemplary method includes receiving a notice to invalidate client DNS resolver cache information for a domain name, accessing a list of client subscribers to an invalidation service for the domain name and issuing an instruction to the client subscribers to invalidate their respective client DNS resolver cache information for the domain name. An exemplary method includes receiving a request to resolve a domain name, resolving the domain name and transmitting information for the resolved domain name and additional information for at least one other domain name. Other methods, devices and systems are also disclosed.

Claims

1. A method, implemented by a computing device, the method comprising:

booting the computing device;

in response to the booting, accessing a file that comprises domain names; and

resolving at least one of the domain names by issuing a request to a server wherein the resolving occurs as a background process.

2. The method of claim 1 wherein the background process comprises a process decoupled from any user initiated request to resolve a domain name.

3. The method of claim 1 wherein the background process comprises a process decoupled from any user application initiated request to resolve a domain name.

4. The method of claim 1 wherein the background process commences in response to the booting.

5. The method of claim 1 wherein the background process commences in response to the accessing.

6. The method of claim 1 wherein the resolving causes updated information, associated with the domain name, to be stored locally on the computing device.

7. The method of claim 1 wherein the resolving selects one of the domain names according to one or more priority criteria.

8. The method of claim 1 wherein the resolving prioritizes the domain names according to their respective frequency of access prior to the booting.

9. The method of claim 1 wherein the resolving prioritizes the domain names according to their respective likelihood of being invalid on a future domain name resolution request.

10. The method of claim 1 wherein the accessing and the resolving occur as an operating system service.

11. One or more computer-readable media comprising processor executable instructions to perform the accessing and the issuing of claim 1 as a background process.

12. A method, implemented by a computing device, the method comprising:

receiving a notice to invalidate client DNS resolver cache information for a domain name;

accessing a list of client subscribers to an invalidation service for the domain name; and

issuing an instruction to the client subscribers to invalidate their respective client DNS resolver cache information for the domain name.

13. The method of claim 12 wherein the instruction comprises changing a TTL for the domain name.

14. The method of claim 12 wherein the instruction comprises setting a TTL for the domain name to zero.

15. The method of claim 12 further comprising triggering each of the client subscribers to issue a request to resolve the domain name.

16. The method of claim 12 wherein the issuing further comprises providing new resolution information for the domain name.

17. One or more computer-readable media comprising processor-executable instructions to perform the method of claim 12.

18. A method, implemented by a computing device, the method comprising:

receiving a request to resolve a domain name;

resolving the domain name; and

transmitting information for the resolved domain name and additional information for at least one other domain name.

19. The method of claim 18 wherein the at least one other domain name comprises a domain name associated with a group of client selected domain names.

20. One or more computer-readable media comprising processor-executable instructions to perform the method of claim 18.
