Project how long an IPv6 migration will take at the current pace and what remains dual-stacked.
A linear burn-down turns the current rate into a completion date. The same figure tells you how long you will be paying to operate two stacks in parallel. Dual-stack duration is the real cost of a transition, because every extra month means duplicated ACLs, duplicated monitoring and two failure modes for every service.
IPv6 Transition
months remaining = ceil(remaining services ÷ services migrated per month); completion = migrated ÷ total.

This calculator takes 3 inputs: Services in scope, Already IPv6-enabled, Services migrated per month. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
