Moving a network from IPv4 to IPv6 usually requires a transition from one standard to another. Trying to make a “big bang” adoption as is sometimes done with enterprise software is not recommended. Instead, running dual stacks to support both IPv4 and IPv6 can provide a fair degree of flexibility at the cost of additional device resources and some additional management overhead. Translating IPv6 to IPv4 protocols may be an option in some cases, such as when NAT is not used, and tunneling is another supported method. No one approach is best for every situation, and your requirements will dictate the appropriate solution for your environment. However, the dual‐stack approach can provide a good balance of functionality versus management overhead in many cases.
