Analysis of Potential Solutions for Revealing a Host Identifier in Shared Address Deployments
RFC 6967, “Analysis of Potential Solutions for Revealing a Host Identifier in Shared Address Deployments”, is an Informational document published in June 2013 by M. Boucadair, J. Touch, P. Levis, R. Penno. The canonical text is published by the RFC Editor.
Abstract
This document is a collection of potential solutions for revealing a host identifier (denoted as HOST_ID) when a Carrier Grade NAT (CGN) or application proxies are involved in the path. This host identifier could be used by a remote server to sort packets according to the sending host. The host identifier must be unique to each host under the same shared IP address.
This document analyzes a set of potential solutions for revealing a host identifier and does not recommend a particular solution, although it does highlight the hazards of some approaches.
What “Informational” means
Published for the general information of the community. It does not define an IETF standard and carries no standards-track status.
