Abstract

Claims (43)

1. A method comprising the steps of:

receiving a request from a network device, said request including an IP address of said network device;

generating a domain name for locating a device configured to process a DNS query, said domain name corresponding to said IP address;

sending said domain name to said network device;

generating and sending a DNS query including said domain name and at least one local DNS setting of said network device from said network device to said device configured to process said DNS query;

processing an association between said IP address and said at least one local DNS setting of said network device;

determining whether at least one of a current device IP address and current local DNS setting matches to a table of previously stored associations of approved prior IP addresses and prior local DNS settings; and

notifying said network device that said at least one of a current device IP address and current local DNS setting may be at risk when it is determined that there is no match in said table.

2. The method, as set forth in claim 1 , wherein said device is configured to process said DNS query includes said device configured to at least one of a store, forward, analyze, monitor, validate, and authenticate said DNS query.

3. The method, as set forth in claim 1 , wherein said device processing said association between said IP address and said at least one local DNS setting includes said device at least one of a storing, forwarding, analyzing, monitoring, validating, and authenticating said association between said IP address and said at least one local DNS setting.

4. The method, as set forth in claim 1 , further including the storage of all determined data as discovered.

5. The method, as set forth in claim 1 , further including the step of:

allowing said network resource to access content from said device when it is determined that there is at least one match in said table.

6. The method, as set forth in claim 1 , further including the step of analyzing determined data in such context as discovered and comparison with predictable norms, inferable norms and/or previously discovered associations and contexts.

7. The method, as set forth in claim 1 , further including the step of:

generating said domain name in response to said network device receiving said first request.

8. The method, as set forth in claim 1 , further including the step of:

generating said DNS query in response to said network device receiving said domain name.

9. The method, as set forth in claim 1 , further including the step of:

storing said association between said IP address and said local DNS settings of said network device in response to said device receiving said second request from said network device.

10. The method, as set forth in claim 1 , further including the step of: generating said domain name.

11. The method, as set forth in claim 10 , further including the step of:

generating a subdomain from said IP address.

12. The method, as set forth in claim 1 , further including the step of: receiving said request from a user agent of said network device.

13. A method comprising:

receiving a first request for a first content from a second network device, said first request including a first domain name for locating a first network device and an IP address of said second network device;

generating a second content including a second domain name for locating a domain name server, said second domain name corresponding to said IP address and said first domain name;

sending said first content and said second content to said second network device;

generating a second request including said second domain name and at least one local DNS setting of said second network device;

said second network device sending said second request to a domain name server;

said domain name server storing an association between said IP address and said at least one local DNS setting of said second network device;

determining whether at least one of a current device IP address and current local DNS setting matches to a table of previously stored associations of approved prior IP addresses and prior local DNS settings; and

notifying said network device that said at least one of a current device IP address and current local DNS setting may be at risk when it is determined that there is no match in said table.

14. The method, as set forth in claim 13 , further including the step of:

generating said second content in response to said first network device receiving said first request.

15. The method, as set forth in claim 13 , further including the step of:

generating said second request in response to said second network device receiving said second content.

16. The method, as set forth in claim 13 , further including the step of:

storing said association between said IP address and said local DNS settings of said second network device in response to said domain name server receiving said second request from said second network device.

17. The method, as set forth in claim 13 , further including the step of:

generating said second domain name.

18. The method, as set forth in claim 17 , further including the step of:

generating a subdomain from said IP address and appending said first domain name to said subdomain.
