11.7.2 Correspondent Registration
                    
(snip)
                    
   If the mobile node wants to ensure that its new care-of address has
   been entered into a correspondent node's Binding Cache, the mobile
   node needs to request an acknowledgement by setting the Acknowledge
   (A) bit in the Binding Update.
