Broadcast addresses do not exist in IPv6? These have been replaced by “multicast addresses,” which serve the same function but in a much more efficient manner...
In IPv6 mobility does not have the problem of unbalanced routing as like in IPv4 packages, so that a mobile connection is so efficient as a normal connection. This is due to there is a process through which the mobile node can inform the node which communicates to which is the address in the new network and use this address for their communication.
