Mobility Support in IPv6

“…The Home Address destination option could be used to direct response traffic toward a node whose IP address appears in the option. In this case, ingress filtering would not catch the forged "return address" [36,32].…”

“…For further information about the design rationale of the return routability procedure, see [27,34,33,32]. The mechanisms used have been adopted from these documents.…”

Host Mobility with the Host Identity Protocol

“…In fact, a malicious peer host may be intentionally giving bogus addresses in order to cause a packet flood towards the target addresses [RFC4225]. Therefore, the HIP host needs to first check that the peer is reachable at the new address.…”

GIST: General Internet Signalling Transport

“…Therefore, consistency between GIST and network routing state has to be ensured by directly interacting with the IP routing mechanisms to ensure that the signalling peers are the appropriate ones for any given flow. An overview of security issues and techniques in this context is provided in [37].…”
