Abstract
Techniques for using Prefix Address Translation (PAT), Mobile Internet Protocol (MIP), and/or other techniques to anonymize server-side addresses in data communications. Rather than allowing a server and/or endpoint have visibility of a client IP address of a client device accessing the server and/or endpoint, a virtual network service instead returns a PAT IP address that is mapped to the client device and/or the endpoint device. In this way, IP addresses of clients devices are obfuscated by the virtual network. The client device may then communicate data packets to the server and/or endpoint using the PAT IP address as the source address, and the virtual network service that works in conjunction with the server and/or endpoints can convert the PAT IP address to the actual IP address of the client for return packets using PAT and forward the return packet onto the client device.
