IPv6 Readiness Calculator
Score how ready your estate is for IPv6 across addressing, transport, applications, security and monitoring.
About IPv6 Readiness Calculator
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
Worked example
With the default values below, IPv6 Readiness Calculator returns Readiness Score of 66.5. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits
- The result is derived only from the 5 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 1 decimal place, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
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.
