Abstract

Methods and systems for DNS resolution are provided. A method for DNS resolution may include identifying a domain name to be resolved. The method may further include providing resolver information associated with the identified domain name. The resolver information indicates that a global DNS resolver is available to resolve the identified domain name. A further embodiment may include requesting DNS resolution of the identified domain name with the global DNS resolver without using a local DNS resolver. A system for DNS resolution may include a domain identification module, a resolver information module and a resolution requester.

Claims

1. A computing device-implemented method for domain name system (DNS) resolution comprising:

identifying a domain name to be resolved; and

providing, with a first computing device, resolver information associated with the domain name to a second computing device, wherein the resolver information indicates that a global DNS resolver is to be used by the second computing device to resolve the identified domain name, without checking, by the first computing, device, whether the domain name is resolvable by a local DNS resolver.

2. The method of claim 1, further comprising requesting, by the second computing device, DNS resolution of the identified domain name with the global DNS resolver without using the local DNS resolver.

3. The method of claim 1, further comprising requesting, by the second computing device, DNS resolution of the identified domain name with the global DNS resolver prior to using the local DNS resolver.

4. The method of claim 1, farther comprising automatically requesting, by the second computing device, DNS resolution of the identified domain name with the global DNS resolver based on the resolver information.

5. The method of claim 1, further comprising determining, by the second computing device, whether the global DNS resolver is trusted.

6. The method of claim 1, further comprising receiving, by the second computing device, a selection of a global DNS resolver.

7. The method of claim 1, further comprising:

requesting, by the second computing device, DNS resolution of the identified domain name with two or more DNS resolvers; and

selecting a resolution that is provided first.

8. The method of claim 1, further comprising requesting, by the second computing device, DNS resolution of the identified domain name based on header information.

9. The method of claim 1, further comprising annotating, by the first computing device, a uniform resource locator (URL) with the resolver information.

10. A computing device-implemented method for domain name system (DNS) resolution comprising:

identifying a domain name to be resolved;

annotating, by a first computing device, an HTTP header with resolver information associated with the domain name; and

providing, by the first computing device, the annotated HTTP header to a second computing device, wherein the resolver information indicates that a global DNS resolver is to be used by the second computing device to resolve the identified domain name.

11. A system for domain name system (DNS) resolution comprising:

a domain identification module configured to identify a domain name to be resolved; and

a resolver information module, implemented on a first computing device, configured to receive resolver information associated with the identified domain name from a second computing device, wherein the resolver information indicates that a global DNS resolver is to be used by the first computing device to resolve the identified domain name without checking, the first computing device, whether the domain name is resolvable by a local DNS resolver.

12. The system of claim 11, further comprising a resolution requester configured to request DNS resolution of the identified domain name with the global DNS resolver without using the local DNS resolver.

13. The system of claim 11, further comprising a resolution requester configured to request DNS resolution of the identified domain name with the global DNS resolver prior to using the local DNS resolver.

14. The system of claim 11, further comprising a resolution requester configured to automatically request DNS resolution of the identified domain name with the global DNS resolver based on the resolver information.

15. The system of claim 11, wherein the resolver information module is further configured to determine whether the global DNS resolver is trusted.

16. The system of claim 11, wherein the resolver information module is further configured to receive a selection of a global DNS resolver.

17. The system of claim 11, further comprising a resolution requester configured to request DNS resolution of the identified domain name with two or more DNS resolvers, wherein the resolver information module is further configured to select a resolution that is provided first and wherein the two or more DNS resolvers includes at least one global DNS resolver.

18. The system of claim 11, further comprising a resolution requester configured to request DNS resolution of the identified domain name based on header information.

19. The system of claim 11, wherein the resolver information module is further configured to annotate a uniform resource locator (URL) with the resolver information.

20. A system for domain name system (DNS) resolution comprising:

a domain identification module configured to identify a domain name to be resolved; and

a resolver information module, implemented on a first computing device, configured to;

receive an HTTP header with annotated resolver information from a second computing device, wherein the resolver information is associated with the identified domain name, and wherein the resolver information indicates that a global DNS resolver is to be used by the first computing device to resolve the identified domain name.

21. A computing device-implemented method for domain name system (DNS) resolution comprising:

identifying a domain name to be resolved; and

determining from DNS resolution records, with a first computing device, that a global DNS resolver is to be used by a second computing device to resolve the identified domain name without using a local DNS resolver and without checking, by the second computing device, whether the domain name is resolvable by the local DNS resolver.
