WebIPv6 Extension Headers In IPv6, optional internet-layer information is encoded in separate headers that may be placed between the IPv6 header and the upper- layer header in a packet. There is a small number of such extension headers, each one identified by a distinct Next Header value. http://www.tcpipguide.com/free/t_IPv6DatagramMainHeaderFormat-2.htm

Value 59 (No Next Header) in the Next Header field indicates that there is no next header whatsoever following this one, not even a header of an upper-layer protocol.
