    abstract =  {In IPv6, optional internet-layer information is encoded in separate headers that may be placed between the IPv6 header and the transport-layer header. There are a small number of such extension headers currently defined. This document describes the issues that can arise when defining new extension headers and discusses the alternate extension mechanisms in IPv6. It also provides a common format for defining any new IPv6 extension headers, if they are needed. {[}STANDARDS-TRACK{]}},
