Hello Jen

If you tell the router then in most cases it will adapt without a problem. In practice we (routers) end up with too many addresses when we store a great many temporary ones that the hosts do not use anymore. You need to realize that those addresses and their bindings are published, e.g., via BGP route type 2. 

Regards,

Pascal
