The Hop-by-Hop option header is a type of IPv6 extension header that has been defined in the IPv6 protocol specification. The contents of this header need to be processed by every node along the path of an IPv6 datagram.This draft highlights the characteristics of this extension header which make it prone to Denial of Service attacks and proposes solutions to minimize such attacks.
