Processor Bi, Wu and Yao,

<   If the node is an IPv4 node, the only different case is DHCP.  The
<   node cannot use a CGA address to send a DHCP solicitation.  This can
<  be solved by using the address as an identifier, but not as a
<   locator.  The CGA address in contained in the packet as an option,
<   and the host id of the IPv4 address is the hash of the CGA address.
<  The signature is computed on the whole packet.

Here, I wonder whether the host id of the IPv4 address created by the hash of the CGA address will bring a collision. In other words, the host id of the IPv4 address may already be used. Perhaps, it should has a duplicate detection.

Best regards.
