Systems and methods for enhancing domain-name-server responses
A computer-implemented method for enhancing domain-name-server responses may include: 1) receiving a domain-name-system request, 2) identifying a domain of the domain-name-system request, 3) retrieving classification information relating to the domain from a third-party system, and 4) including the classification information in a response to the domain-name-system request. Various other methods, systems, and computer-readable media are also disclosed.
1. A computer-implemented method for enhancing domain-name-server responses, at least a portion of the method being performed by a computing device comprising at least one processor, the method comprising:
receiving a domain-name-system request;
identifying a domain of the domain-name-system request;
retrieving classification information relating to the domain from a third-party system, wherein the classification information comprises information that is separate from or additional to information that is required to resolve the IP address;
including both the information required to resolve the IP address and the classification information in a response to the domain-name-system request;
identifying a time-to-live value for the classification information;
including the time-to-live value for the classification information in the response by:
identifying a time-to-live value for a resolution of the domain;
determining that the time-to-live value for the classification information is less than the time-to-live value for the resolution of the domain;
using the time-to-live value for the classification information as the time-to-live value for the resolution of the domain in the response.
2. The computer-implemented method of claim 1 , wherein retrieving the classification information comprises:
identifying an Internet classification provider;
transmitting information identifying the domain to the Internet classification provider;
receiving the classification information from the Internet classification provider.
3. The computer-implemented method of claim 2 , wherein identifying the Internet classification provider comprises identifying a plug-in for the Internet classification provider.
4. The computer-implemented method of claim 1 , wherein retrieving the classification information comprises:
identifying a time-to-live value for the classification information;
determining that the time-to-live value for the classification information has not expired;
retrieving the classification information from a local cache.
5. The computer-implemented method of claim 1 , wherein including the time-to-live value for the classification information in the response comprises including the time- to-live value for the classification information as a separate record within the response.
6. The computer-implemented method of claim 1 , wherein the classification information comprises at least one of:
a rating;
a trust level;
a content category.
7. The computer-implemented method of claim 1 , wherein including the classification information in the response comprises including the classification information in a text record in the response.
8. The computer-implemented method of claim 1 , wherein:
the domain-name-system request is made within a domain-name-system hierarchy;
the third-party system comprises a system outside of the domain-name-system hierarchy.
9. A system for enhancing domain-name-server responses, the system comprising:
a receiving module programmed to receive a domain-name-system request;
an identification module programmed to identify a domain of the domain-name-system request;
a retrieval module programmed to retrieve classification information relating to the domain from a third-party system, wherein the classification information comprises information that is separate from or additional to information that is required to resolve the IP address;
a response module programmed to:
include both the information required to resolve the IP address and the classification information in a response to the domain-name-system request;
identify a time-to-live value for the classification information;
include the time-to-live value for the classification information in the response by:
identifying a time-to-live value for a resolution of the domain;
determining that the time-to-live value for the classification information is less than the time-to-live value for the resolution of the domain;
using the time-to-live value for the classification information as the time-to-live value for the resolution of the domain in the response;
at least one processor configured to execute the receiving module, the identification module, the retrieval module, and the response module.
10. The system of claim 9 , wherein the retrieval module is programmed to retrieve the classification information by:
identifying an Internet classification provider;
transmitting information identifying the domain to the Internet classification provider;
receiving the classification information from the Internet classification provider.
11. The system of claim 10 , wherein the retrieval module is programmed to identify the Internet classification provider by identifying a plug-in for the Internet classification provider.
12. The system of claim 9 , wherein the retrieval module is programmed to retrieve the classification information by:
identifying a time-to-live value for the classification information;
determining that the time-to-live value for the classification information has not expired;
retrieving the classification information from a local cache.
13. The system of claim 9 , wherein the response module is programmed to include the time-to-live value for the classification information in the response by including the time-to-live value for the classification information as a separate record within the response.
14. The system of claim 9 , wherein the classification information comprises at least one of:
a rating;
a trust level;
a content category.
15. The system of claim 9 , wherein the response module is programmed to include the classification information in the response by including the classification information in a text record in the response.
16. A non-transitory computer-readable-storage medium comprising one or more computer-executable instructions that, when executed by at least one processor of a computing device, cause the computing device to:
receive a domain-name-system request;
identify a domain of the domain-name-system request;
retrieve classification information relating to the domain from a third-party system, wherein the classification information comprises information that is separate from or additional to information that is required to resolve the IP address;
include both the information required to resolve the IP address and the classification information in a response to the domain-name-system request;
identify a time-to-live value for the classification information;
include the time-to-live value for the classification information in the response by:
identifying a time-to-live value for a resolution of the domain;
determining that the time-to-live value for the classification information is less than the time-to-live value for the resolution of the domain;
using the time-to-live value for the classification information as the time-to-live value for the resolution of the domain in the response.
