As of August 2026, 54.27% of 5,340,321 monitored website hosts now support both IPv4 and IPv6 protocols, a steady increase from 50.14% in March 2025. The data confirms that a significant portion of the internet remains restricted to legacy IPv4, with approximately 2.44 million hosts still lacking IPv6 capability.
Why it matters
The transition to IPv6 is essential for managing the exhaustion of unique IPv4 addresses, yet current growth remains largely dependent on infrastructure providers rather than independent deployments. This shift highlights how centralized cloud and mail services are carrying the burden of modernizing global network connectivity.
IPv6 availability reached 64.71% for nameservers, while web and mail services trailed at 30.06% and 32.85%, respectively. The mail service metric shows a 12.92 percentage point increase since January 2022, largely attributed to migrations to managed platforms like Microsoft 365 and Google Workspace.
The players
IPv6Matrix
An analytical project focused on tracking the global deployment and adoption rates of IPv6 network protocols.
Internet Society Pulse
A research initiative that provides data-driven analysis on internet health, connectivity trends, and infrastructure evolution.
Google Workspace
A cloud-based suite of productivity and communication tools that contributes to IPv6 adoption through standardized platform migrations.
Microsoft 365
An enterprise cloud platform whose service migration requirements have increased the prevalence of IPv6-capable mail servers.
The details
The increase in IPv6 deployment is primarily achieved through dual-stack configurations, which allow a network interface to process both IPv4 and IPv6 traffic simultaneously. Major hosting platforms and CDNs, or content delivery networks—geographically distributed servers that cache content for faster delivery—provide this capability by default to their customers. This masks the reality that many individual web services have not manually configured their infrastructure for IPv6, instead relying on the provider's underlying hardware capabilities.
Timeline
January 2022: Dual-stack support was recorded at 41.35%.
March 2025: Dual-stack support grew to 50.14%.
March 2026: Web service IPv6 availability was 30.06% and mail services were 32.85%.
August 2026: Dual-stack support reached 54.27% across 5,340,321 hosts.
September 22, 2026: Internet Society Pulse published the analysis.
The Tech Race
This development marks a steady progression in the multi-decade transition away from the legacy IPv4 standard following the IANA IPv4 address pool exhaustion. The slow pace of adoption highlights a persistent gap between platform-level IPv6 readiness and the configuration of individual web services.
Most users will see no change, as the transition to IPv6 primarily occurs at the backend infrastructure level managed by CDNs and cloud providers. The persistence of 2.44 million IPv4-only hosts suggests that legacy compatibility requirements remain the primary barrier for smaller, self-managed server environments.
The takeaway
The data suggests that global IPv6 adoption is now a function of platform-as-a-service ubiquity rather than a deliberate upgrade cycle by individual site owners. Watch for future reports from Internet Society Pulse to see if the rate of IPv6 adoption accelerates as hardware providers phase out IPv4-exclusive support cycles.
What happens next
An upcoming crawler and server update from the research project is expected to provide more granular analysis on ccTLD and country-specific IPv6 deployment metrics.
