Scenarios with Host Identification Complications
Abstract
This document describes a set of scenarios in which complications
when identifying which policy to apply for a host are encountered.
This problem is abstracted as "host identification". Describing
these scenarios allows commonalities between scenarios to be
identified, which is helpful during the solution design phase.
This document does not include any solution-specific discussions.
IESG Note
This document describes use cases where IP addresses are overloaded
with both location and identity properties. Such semantic
overloading is seen as a contributor to a variety of issues within
the routing system [RFC4984]. Additionally, these use cases may be
seen as a way to justify solutions that are not consistent with IETF
Best Current Practices on protecting privacy [BCP160] [BCP188].
