VIRTUAL SERVER ADDRESS SELECTION
This abstract first appeared for US patent application 18885330 titled 'VIRTUAL SERVER ADDRESS SELECTION
Original Abstract Submitted
Techniques for varying locations of virtual networks associated with endpoints using Network Address Translation (NAT), Mobile Internet Protocol (MIP), and/or other techniques in conjunction with Domain Name System (DNS). Rather than having DNS provide a client device with an IP address of an endpoint device, such as a server, the DNS instead returns a virtual IP (VIP) address that is mapped to the client device and the endpoint device. The VIP address may be selected based on a number of factors (e.g., power usage, privacy requirements, virtual distances, etc.). In this way, IP addresses of servers are obfuscated by a virtual network of VIP addresses that can be periodically rotated and/or load balanced. The client device may then communicate data packets to the server using the VIP address as the destination address, and a virtual network service that works in conjunction with DNS can convert the VIP address to the actual IP address of the server using NAT and forward the data packet onto the server.
