What Does Dual Stack Network Mean?
A dual stack network is a network in which all of the nodes are both IPv4 and IPv6 enabled. This is especially important at the router, as the router is typically the first node on a given network to receive traffic from outside of the network.Many experts believe that network infrastructure will shift from IPv4 to IPv6 in order to provide more adress space and serve growing global connecitivity. Dual stack networks are one of the many IPv4 to IPv6 migration strategies that have been presented in recent years.
