Abstract

An exemplary system may configure network settings of an unreachable host. In one embodiment, the system determines that a first host on a network is unreachable using a first communication protocol. The system selects a second host on the network that is reachable using the first communication protocol. The second host on the network can reach the first host using a second communication protocol. The system provides a communication to the second host on the network using the first communication protocol. The communication causes the second host to access the first host on the network using the second communication protocol.

Claims

1. A method comprising:

determining, by a processing device, that a first host on a network is unreachable using a first communication protocol;

selecting a second host on the network that is reachable using the first communication protocol in view of a proximity between the first host and the second host, wherein the second host on the network can reach the first host using a second communication protocol; and

providing, by the processing device, a communication to the second host on the network using the first communication protocol, wherein the communication causes the second host to access the first host on the network in view of a scope associated with the first host to cause the second host to configure a network configuration of the first host.

2. The method of claim 1, wherein selecting a second host on the network that is reachable comprises:

selecting the second host from one or more hosts on a same segment of the network as the first host in view of the proximity, wherein the processing device can communicate with the second host using the first communication protocol.

3. The method of claim 1, wherein providing the communication to the second host on the network using the first communication protocol comprises:

providing a command to the second host, wherein the command instructs the second host to securely access the first host using the second communication protocol, wherein the network configuration is associated with the first communication protocol.

4. The method of claim 3, wherein the command further instructs the second host to reboot the first host to cause the scope associated with the first host to be configured.

5. The method of claim 3, further comprising:

providing the scope associated with the first host to the second host, wherein the scope for the first host is in view of another network configuration of the first host and a media access control (MAC) address associated with the first host, wherein the another network configuration of the first host is associated with the second communication protocol.

6. The method of claim 1, wherein the first communication protocol is associated with a protocol module in a protocol stack and the second communication protocol is associated with the protocol module in the protocol stack.

7. The method of claim 1, wherein the first communication protocol is Internet Protocol version 4 (IPv4) and the second communication protocol is Internet Protocol version 6 (IPv6).

8. A non-transitory computer readable storage medium having instructions that, when executed by a processing device, cause the processing device to:

determine, by the processing device, that a first host on a network is unreachable using a first communication protocol;

select a second host on the network that is reachable using the first communication protocol in view of a proximity between the first host and the second host, wherein the second host on the network can reach the first host using a second communication protocol; and

provide, by the processing device, a communication to the second host on the network using the first communication protocol, wherein the communication causes the second host to access the first host on the network using the second communication protocol in view of a scope associated with the first host to cause the second host to configure a network configuration of the first host.

9. The non-transitory computer readable storage medium of claim 8, wherein to select a second host on the network that is reachable, the processing device is to:

select the second host from one or more hosts on a same segment of the network as the first host in view of the proximity, wherein the processing device to communicate with the second host using the first communication protocol.

10. The non-transitory computer readable storage medium of claim 8, wherein to provide the communication to the second host on the network using the first communication protocol comprises:

provide a command to the second host, wherein the command instructs the second host to securely access the first host using the second communication protocol, wherein the network configuration is associated with the first communication protocol.

11. The non-transitory computer readable storage medium of claim 10, wherein the command further to instruct the second host to reboot the first host to cause the scope associated with the first host to be configured.

12. The non-transitory computer readable storage medium of claim 10, wherein the processing device is further to:

provide the scope associated with the first host to the second host, wherein the scope for the first host is in view of another network configuration of the first host and a media access control (MAC) address associated with the first host, wherein the another network configuration of the first host is associated with the second communication protocol.

13. The non-transitory computer readable storage medium of claim 8, wherein the first communication protocol is associated with a protocol module in a protocol stack and the second communication protocol is associated with the protocol module in the protocol stack.

14. The non-transitory computer readable storage medium of claim 8, wherein the first communication protocol is Internet Protocol version 4 (IPv4) and the second communication protocol is Internet Protocol version 6 (IPv6).

15. A computing device comprising:

a memory; and

a processing device operatively coupled to the memory, wherein the processing device is to;

determine that a first host on a network is unreachable using a first communication protocol;

select a second host on the network that is reachable using the first communication protocol in view of a proximity between the first host and the second host, wherein the second host on the network can reach the first host using a second communication protocol; and

provide a communication to the second host on the network using the first communication protocol, wherein the communication causes the second host to access the first host on the network in view of a scope associated with the first host to cause the second host to configure a network configuration of the first host.

16. The computing device of claim 15, wherein to select a second host on the network that is reachable, the processing device is further to:

select the second host from one or more hosts on a same segment of the network as the first host in view of the proximity, wherein the processing device can communicate with the second host using the first communication protocol.

17. The computing device of claim 15, the processing device is further to:

provide a command to the second host, wherein the command to instruct the second host to securely access the first host using the second communication protocol, wherein the network configuration is associated with the first communication protocol.

18. The computing device of claim 17, wherein the command further to instruct the second host to reboot the first host to cause the scope associated with the first host to be configured.

19. The computing device of claim 17, wherein the processing device is further to:

provide the scope associated with the first host to the second host, wherein the scope for the first host is in view of another network configuration of the first host and a media access control (MAC) address associated with the first host, wherein the another network configuration of the first host is associated with the second communication protocol.

20. The computing device of claim 15, wherein the first communication protocol is associated with a protocol module in a protocol stack and the second communication protocol is associated with the protocol module in the protocol stack.
