The assertion stems from the original mandated use of IPsec in host-to-host communication, as specified in RFC 2401. It is a natural requirement in the context of IPv6’s intent to provide a new infrastructure that supports peer-to-peer applications. If this mandate would be enforced by all hosts, properly implemented by all applications, and a reliable and efficient key-exchange system would be universally adopted, it would mean a more secure data transport. The consistent use of IPsec on host-to-host communication would also enable network operators to track sources of attacks. Nevertheless, ...
