AERO provides a fixed link-local address that is formed from a prefix
received by DHCPv6 Prefix Delegation (PD). Once the AERO Client is
given a PD (either IPv6 or IPv4) it can form an AERO link-local address
that stays the same wherever the Client moves and with no need to
perform Duplicate Address Detection (DAD). It makes IPv6 ND
simple and seamless.
