Addressing plan complete = 80 %; Network devices IPv6-capable = 90 %; Applications IPv6-tested = 55 %; Security policy parity with IPv4 = 60 %; Monitoring covers IPv6 = 45 %

How it works
Each dimension is scored as a completion percentage and combined with weights that reflect where IPv6 projects actually stall — applications and security policy rather than routers. Turning on IPv6 without security parity or monitoring coverage creates an unobserved, unfiltered path into the same servers, which is worse than not enabling it at all.
Formula
IPv6 Readiness
score = 0.20×addressing + 0.20×transport + 0.25×applications + 0.20×security + 0.15×monitoring.
- applications
- Weighted highest because application support is the usual blocker
- security
- Policy parity between the two stacks
Frequently Asked Questions
How is IPv6 Readiness calculated?
score = 0.20×addressing + 0.20×transport + 0.25×applications + 0.20×security + 0.15×monitoring. Each dimension is scored as a completion percentage and combined with weights that reflect where IPv6 projects actually stall — applications and security policy rather than routers.
Why does IPv6 Readiness matter?
Turning on IPv6 without security parity or monitoring coverage creates an unobserved, unfiltered path into the same servers, which is worse than not enabling it at all.
What values do I need to enter?
This calculator takes 5 inputs: Addressing plan complete, Network devices IPv6-capable, Applications IPv6-tested, Security policy parity with IPv4, Monitoring covers IPv6. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
