LISP EID Anonymity
draft-ietf-lisp-eid-anonymity-04
Abstract
This specification will describe how ephemeral LISP EIDs can be used
to create source anonymity. The idea makes use of frequently
changing EIDs much like how a credit-card system uses a different
credit-card numbers for each transaction.

1. Introduction
The LISP architecture [RFC6830] specifies two namespaces, End-Point
IDs (EIDs) and Routing Locators (RLOCs). An EID identifies a node in
the network and the RLOC indicates the EID's topological location.
Typically EIDs are globally unique so a end-node system can connect
to any other end-node system on the Internet. Privately used EIDs
are allowed when scoped within a VPN but must always be unique within
that scope. Therefore, address allocation is required by network
administration to avoid address collisions or duplicate address use.
