   Note

 IPv6 anycast addresses are defined in "IP Version 6 Addressing
 Architecture" [RFC4291]. [RFC2526] further defines a set of
 reserved subnet anycast addresses. These are the highest 128
 interface identifier values, within each subnet.  The syntax
 and rules for assigning new IPv6 reserved subnet anycast addresses
 are defined in [RFC2526].  These addresses are assigned in descending
 order.
