Abstract

Claims (48)

1. A method in a virtual private network (VPN), the method comprising:

receiving, at a VPN server, a first data request for the VPN server to retrieve first data of interest from a first host device;

selecting, by the VPN server, a first exit internet protocol (IP) address to transmit a first query for retrieving the first data of interest from the first host device;

transmitting, by the VPN server to the first host device based at least in part on selecting the first exit IP address, the first query for retrieving the first data of interest from the first host device;

determining, by the VPN server based at least in part on transmitting the first query, that the first exit IP address is blocked by the first host device;

suspending, by the VPN server based at least in part on determining that the first exit IP address is blocked by the first host device, utilization of the first exit IP address for retrieving the first data of interest from the first host device;

selecting, by the VPN server, the first exit IP address to transmit a second query for retrieving second data of interest from a second host device; and

transmitting, by the VPN server to the second host device based at least in part on selecting the first exit IP address, the second query for retrieving the second data of interest from the second host device.

2. The method of claim 1 , further comprising:

ending suspension of utilization of the first exit IP address for retrieving the first data of interest from the first host device based at least in part on determining that the first host device has ceased to block the first exit IP address.

3. The method of claim 1 , further comprising:

determining, periodically, whether the first host device has ceased to block the first exit IP address.

4. The method of claim 1 , further comprising:

selecting, based at least in part on determining that the first exit IP address is blocked by the first host device, a second exit IP address for retrieving the first data of interest from the first host device, the second exit IP address being different from the first exit IP address.

5. The method of claim 1 , further comprising:

utilizing, by the VPN server, a second exit IP address to transmit a third query for retrieving the first data of interest from the first host device, the second exit IP address being different from the first exit IP address.

6. The method of claim 1 , wherein determining that the first exit IP address is blocked by the first host device includes receiving, based at least in part on transmitting the first query, a response from the first host device indicating that the first host device has declined to provide the first data of interest.

7. The method of claim 1 , further comprising:

determining a negative correlation between the first exit IP address and the first host device to indicate that the first exit IP address is not to be utilized for retrieving the first data of interest from the first host device.

8. A virtual private network (VPN) server, comprising:

a memory; and

a processor communicatively coupled to the memory, the memory and the processor being configured to:

receive a first data request for the VPN server to retrieve first data of interest from a first host device;

select a first exit internet protocol (IP) address to transmit a first query for retrieving the first data of interest from the first host device;

transmit, to the first host device based at least in part on selecting the first exit IP address, the first query for retrieving the first data of interest from the first host device;

determine, based at least in part on transmitting the first query, that the first exit IP address is blocked by the first host device;

suspend, based at least in part on determining that the first exit IP address is blocked by the first host device, utilization of the first exit IP address for retrieving the first data of interest from the first host device;

select the first exit IP address to transmit a second query for retrieving second data of interest from a second host device; and

transmit, to the second host device based at least in part on selecting the first exit IP address, the second query for retrieving the second data of interest from the second host device.

9. The VPN server of claim 8 , wherein the memory and the processor are configured to end suspension of utilization of the first exit IP address for retrieving the first data of interest from the first host device based at least in part on determining that the first host device has ceased to block the first exit IP address.

10. The VPN server of claim 8 , wherein the memory and the processor are configured to determine, periodically, whether the first host device has ceased to block the first exit IP address.

11. The VPN server of claim 8 , wherein the memory and the processor are configured to select, based at least in part on determining that the first exit IP address is blocked by the first host device, a second exit IP address for retrieving the first data of interest from the first host device, the second exit IP address being different from the first exit IP address.

12. The VPN server of claim 8 , wherein the memory and the processor are configured to utilize a second exit IP address to transmit a third query for retrieving the first data of interest from the first host device, the second exit IP address being different from the first exit IP address.

13. The VPN server of claim 8 , wherein, to determine that the first exit IP address is blocked by the first host device, the memory and the processor are configured to receive, based at least in part on transmitting the first query, a response from the first host de vice indicating that the first host device has declined to provide the first data of interest.

14. The VPN server of claim 8 , wherein the memory and the processor are configured to determine a negative correlation between the first exit IP address and the first host device to indicate that the first exit IP address is not to be utilized for retrieving the first data of interest from the first host device.

15. A non-transitory computer-readable medium configured to store instructions, which when executed by a processor associated with a virtual private network (VPN) server, configure the processor to:

receive a first data request for the VPN server to retrieve first data of interest from a first host device;

select a first exit internet protocol (IP) address to transmit a first query for retrieving the first data of interest from the first host device;

transmit, to the first host device based at least in part on selecting the first exit IP address, the first query for retrieving the first data of interest from the first host device;

determine, based at least in part on transmitting the first query, that the first exit IP address is blocked by the first host device;

suspend, based at least in part on determining that the first exit IP address is blocked by the first host device, utilization of the first exit IP address for retrieving the first data of interest from the first host device;

select the first exit IP address to transmit a second query for retrieving second data of interest from a second host device; and

transmit, to the second host device based at least in part on selecting the first exit IP address, the second query for retrieving the second data of interest from the second host device.

16. The non-transitory computer-readable medium of claim 15 , wherein the processor is configured to end suspension of utilization of the first exit IP address for retrieving the first data of interest from the first host device based at least in part on determining that the first host device has ceased to block the first exit IP address.
