    abstract =  {The Prefix Information Option in the IPv6 Neighbor Discovery Router Advertisement message defines an 8-bit flag field with two flags defined and the remaining 6 bits reserved (Reserved1). RFC 6275 has defined a new flag from this field without creating a IANA registry or updating RFC 4861. The purpose of this document is to request a new IANA registry for the PIO flags. This document updates RFC 4861.},
