I agree with others that this is a very hard thing to estimate.
I will say that we run our dual-stack network (fully deployed since ca.
2012) with exactly the same staffing levels, and actually a slight
reduction in our recurrent budget, as our older IPv4-only network.
I don't think our network is any less reliable, or suffers a higher
level of incidents. This suggests to me that, in our case, IPv6 has
added a very low operational cost. Our incidence of IPv6-related
problems, particularly rogue RA from machines configured for connection
sharing, has actually *decreased* substantially since we deployed native
I don't believe the rollout cost was high. We used refresh cycles to
upgrade to v6-capable gear, and rolled out slowly to grow our team
knowledge. But we don't have detailed cost breakdowns.
