Abstract

Host name data is “looped-back” from a native host name resolver included in a requesting computer system to a name resolution port that is also included in the requesting computer system. A replacement host name resolver monitors the name resolution port for host name data that is incompatible with name resolution techniques utilized by a network. The replacement host name resolver modifies the otherwise incompatible host name data for compatibility with name resolution techniques utilized by the network. Modifying host name data may include changing a transmission protocol associated with the host name data or formatting non-secure host name data for resolution with secure host name resolution techniques. The replacement host name resolver redirects compatible host name data to a module that may cause the host name data to be resolved into a network address. The network address may be provided to the native host name resolver.

Claims

6. The method as recited in claim 1, wherein the act of monitoring a name resolution port of the requesting computer system for receiving host name data in a host name resolution protocol comprises the following:

an act of monitoring a name resolution port of the requesting computer system that is associated with an IP network.

7. The method as recited in claim 6, wherein the act of monitoring a name resolution port of the requesting computer system that is associated with an IP network comprises the following:

an act of monitoring port 53 of the requesting computer system.

8. The method as recited in claim 1, wherein the act of monitoring a name resolution port of the requesting computer system for receiving host name data in a host name resolution protocol comprises the following:

an act of monitoring a name resolution port for receiving host name data in a host name resolution protocol that is compatible with an IP network.

9. The method as recited in claim 8, wherein the act of monitoring a name resolution port for receiving host name data in a host name resolution protocol that is compatible with an IP network comprises the following:

act of monitoring a name resolution port for host name data contained in one or more UDP packets.

10. The method as recited in claim 1, wherein the act of monitoring a name resolution port of the requesting computer system for receiving host name data in a host name resolution protocol comprises the following:

an act of a replacement host name resolver monitoring a name resolution port for receiving host name data sent from a native host name resolver.

11. The method as recited in claim 1, wherein the act of monitoring a name resolution port of the requesting computer system for receiving host name data in a host name resolution protocol comprises the following:

an act of a re solving computer system monitoring a name resolution port for receiving host name data sent from a native host name resolver.

12. The method as recited in claim 1, wherein the act of rerouting the host name data to a module that may resolve the host name data comprises the following:

an act of a replacement host name resolver rerouting the host name data to a module that may resolve the host name data.

13. The method as recited in claim 1, wherein the act of rerouting the host name data to a module that may resolve the host name data comprises the following:

an act of modifying the host name data so that the host name data is compatible with the module that may resolve the host name data.

14. The method as recited in claim 13, wherein the act of modifying the host name data so that the host name data is compatible with the module that may resolve the host name data the comprises the following:

an act of modifying the protocol used to transport the host name data.

15. The method as recited in claim 14, wherein the act modifying the protocol used to transport the host name data of comprises the following:

an act of modifying the protocol used to transport the host name data from UDP to TCP.

16. The method as recited in claim 13, wherein the act of modifying the host name data so that the host name data is compatible with the module that may resolve the host name data the comprises the following:

an act of modifying the format of host name data that is incompatible with secure DNS so that the host name data be resolved in accordance with secure DNS.

17. The method as recited in claim 1, wherein the act of rerouting the host name data to a module that may resolve the host name data comprises the following:

an act of a replacement host name resolver rerouting the host name data to a module that was identified by entering one or more parameters in a user interface.

18. The method as recited in claim 1, further comprising:

an act of providing the requesting computer system with a network address by resolving the host name data that was rerouted.

19. The method as recited in claim 18, wherein the act of providing the requesting computer system with a network address by resolving the host name data that was rerouted comprises the following:

providing the requesting computer system with a numerical IP address by resolving a domain name that was rerouted.

20. In a requesting computer system that is network connectable to a network, the requesting computer system including a host a name resolver that is not capable of resolving a host name when the requesting computer system is connected to the network, a method for resolving a host name, comprising the following:
