Today, the use of IPv6 anycast is limited. This document proposes a mechanism by which TCP/SCTP and stateful protocols using UDP can securely discover the mapping from an anycast address to a unicast address that can be used until a failure is detected. The mechanism reuses the Mobile IPv6 Return Routability and Binding Update mechanism.
