DualStack Cost Dashboard

A financial dashboard that quantifies the hidden annual cost of running IPv4 alongside IPv6, including address leases, ARP-storm incidents, and dual-stack monitoring overhead.

Target user

CIOs and infrastructure VPs justifying an IPv6 migration budget to the board

Features
  • Annualized cost breakdown of IPv4 address leases versus projected ARP-related outage minutes
  • Trend lines showing dual-stack monitoring time per engineer per quarter, pulled from your ticketing system
  • Side-by-side TCO model comparing staying dual-stack versus adopting the new IPv4-over-IPv6 sentinel approach
  • Board-ready PDF export with charts and a one-page executive summary
Why now

IPv4 address spot prices keep rising while the standards community has just delivered a clean way to retire ARP, so finance leaders finally have the technical path to greenlight the move

Signals · overall 5/10
Demand
4/10

IPv4 lease rates have actually stabilized around $0.40-$0.50/IP/month in 2024-2025 and large-block purchase prices dropped below $20/IP; the 'prices keep rising' narrative is overstated, weakening urgency for a dedicated cost dashboard.2025 IPv4 Price Trends and 2026 Predictions

Whitespace
7/10

Existing IPv6 cost materials (ARIN blog series, Cisco IT case study, OneUptime migration cost guide, Network Direction articles, IR.com guides) are blogs/PDFs, not standalone SaaS dashboards quantifying dual-stack overhead.The Business Case for IPv6-Only Enterprise - ARINHow to Estimate IPv6 Migration Costs - OneUptime

Monetization
4/10

CIO-facing IPv6 justification content is largely free (ARIN, Cisco, vendor blogs); enterprises get TCO numbers from incumbent IPAM/network vendors (Infoblox, Cisco, BlueCat) bundled with existing spend, making a standalone paid dashboard a hard sell.How Cisco IT Is Accelerating Adoption of IPv6IPv4 to IPv6 Migration: Complete Enterprise Guide for 2025

Longevity
5/10

IPv6 migration is a multi-decade transition and ARP-retirement standards the idea hinges on (referenced Hacker News 'Farewell to ARPs' item) did not surface in search, suggesting the 'clean way to retire ARP' catalyst is not a near-term inflection; market will exist but not accelerate soon.Business Case for IPv6 - ARIN

Feasibility
4/10

Quantifying ARP-storm incidents and dual-stack monitoring overhead requires customer-specific telemetry (NMS exports, logs) and validated incident-cost models that don't publicly exist; building the inputs is much harder than the dashboard UI.How to Estimate IPv6 Migration Costs - OneUptime
