“…The per-connection address is not the end of the road either. Researchers extend this idea temporally to propose per-packet address [31,32], and spatially to propose prefix alteration [55][56][57]. The per-packet address means to use a unique address for each packet.…”

Eliminating unnecessary exposure is a principle of server security. The huge IPv6 address space enhances security by making scanning infeasible, however, with recent advances of IPv6 scanning technologies, network scanning is again threatening server security. In this paper, we propose a new model named addressless server, which separates the server into an entrance module and a main service module, and assigns an IPv6 prefix instead of an IPv6 address to the main service module. The entrance module generates a legitimate IPv6 address under this prefix by encrypting the client address, so that the client can access the main server on a destination address that is different in each connection. In this way, the model provides isolation to the main server, prevents network scanning, and minimizes exposure. Moreover it provides a novel framework that supports flexible load balancing, high-availability, and other desirable features. The model is simple and does not require any modification to the client or the network. We implement a prototype and experiments show that our model can prevent the main server from being scanned at a slight performance cost.

“…Prefix alteration means not only the IID part but also the prefix part of a device's address can be varying. It can be achieved by prefix hopping, prefix bouquets, prefix sharing, and variable-length prefix [55,56], or by exploiting mobile IPv6 [57].…”
