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.
