Abstract
Techniques for using Home Addresses, Mobile Internet Protocol (MIP), and/or other techniques in conjunction with Domain Name System (DNS) to obfuscate server-side addresses in data communications. 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 Home Address that is mapped to the client device and at least one server IP address of the endpoint device. In this way, IP addresses of servers are obfuscated by a network mapping of the Home Addresses and the server IP addresses. The client device may then communicate data packets to the server using the Home Addresses as the destination address, and a virtual network service that works in conjunction with DNS can encapsulate the data packet with the server IP addresses and forward the data packet onto the server.
