Today's IP network layer provides little to no protection against misconfiguration or malice. In this research, we show how a network layer based on cryptographically self-certifying addresses can effectively identify and thwart misconfigurations and attacks such as address spoofing, DoS attack, and control-plane hijacking. In addition, the current routing infrastructure fails to identify and utilize a fail-over path to an end host even if the host is multihomed. We show how a network address structure that explicitly encodes multihoming information can improve the network availability.
