<div>I have found more problems with the DHCPv6-PD. The issue is on many home networks where people are using server type hardware such as Windows(TM) networks where DNS is used to locate and secure the network the renumbering event creates
major problems as the on premises DHCPv6 server has no way to understand that a renumber event has occurred. People are very used to the IPv4 RFC 1918 static addressing where nothing on their local internal network will change without notice. The fact that
ISPs can randomly change the internal delegated address without notice is a major problem. That will confuse people and cause problems especially where a customer has equipment such as Windows or Linux servers or other equipment that requires static addressing
or DHCPv6. I understand that for certain operational reasons ISPs need to renumber addresses however I suggest we discourage the practice. We also could modify the RFC to require a message to be sent by CPE to all downstream network devices that a network
renumber event is being scheduled. This can be sent as a multicast message that encodes the date that the renumbering will occur. I realize that we need to understand the security implications of this. This is just one idea that could smooth the renumbering
events when then have to happen for some operational reason. <br>
