   This document recommends ways to reduce forged-origin attack surface
   by prudently limiting the address space that is included in Route
   Origin Authorizations (ROAs).  One recommendation is to avoid using
   the maxLength attribute in ROAs except in some specific cases.  The
   recommendations complement and extend those in RFC 7115.  The
   document also discusses creation of ROAs for facilitating Distributed
   Denial of Service (DDoS) mitigation services.  Considerations related
   to ROAs and origin validation for the case of destination-based
   Remote Triggered Black Hole (RTBH) filtering are also highlighted.
