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 specifies a new IPv6 Extension Header - the Universal Extension Header - that overcomes the aforementioned problem, while enabling the extensibility of IPv6. Finally, this document formally obsoletes RFC 6564.
