The DNAv6 was designed to support fast attachment for a host, which is corresponding to the movement detection part in the mobility management. Since, however, the DNAv6 has supported only DNAv6-capable ARs and DNAv6-capable hosts, an non-DNAv6 host could not support fast handoff function in a DNAv6 network. In this paper, we consider a new method of the fast attachment of non-DNAv6 hosts. To support the non-DNAv6 host in DNAv6 networks, we suggest a novel algorithm, RCA algorithm, where an AR can decide whether a host has the DNAv6 function and whether it has moved to a new link or not, and then the AR can inform the host of new link information. For the RCA algorithm, we proposed to modify the RS message and the Reconf_Link message with addition of some fields. To validate our RCA algorithm and its performance, we have accomplished simulation tests for the ND process, the DNAv6 process and the modified DNAv6 process with our RCA algorithm. In the viewpoints of the attachment delay and complexity, the proposed algorithm gives the better delay performance than the ND process while it presents the less complexity than the DNAv6 process.
