We’re excited to announce the release of ntopng 6.6, available today!
This release focuses on Autonomous Systems (AS) analytics, a major rework of the flow collection engine to provide better correlations and improve performance, and a native ClickHouse Cloud integration. But, as usual, there are many other improvements.
Key Breakthroughs
Autonomous Systems Intelligence
ntopng 6.6 introduces brand new Autonomous Systems dashboards, Sankey visualizations, and comprehensive AS statistics.
You can now easily understand traffic relationships between transit and origin ASes, track top contributors, and visualize AS-level traffic flows in real time.
The release also brings:
- AS ranking detection and alerting with configurable thresholds
- AS traffic rules and conditional aggregation for smarter AS-based management
- Transit-only AS filters and dedicated tables for focused visibility
These new AS analytics turn ntopng into a powerful tool for ISPs, backbone operators, and organizations managing multi-AS environments. This is just the first step (previewed last September) of a long term development including BGP traffic analysis.
Enhanced Flow Collection and Export
We’ve completely reworked the flow collection code, optimizing both performance and memory footprint.
Exporters and probes now have dedicated statistics pages for easier monitoring and troubleshooting.
New capabilities include:
- Native ClickHouse Cloud support with SSL/TLS connections
- Improved historical flow filtering and export
- Direct flows dump mode (
--direct-flows-dump) for real-time export to ClickHouse
These changes make ntopng more reliable and efficient when processing large-scale flow datasets in real time.
Smarter SNMP Management
SNMP device management has been improved across the board:
- SNMP interface roles (core/distribution/access) for better topology visualization
- Bridge MIB integration in the asset inventory
- Optimized SNMP polling and caching to reduce overhead
- CSV import/export with SNMPv3 support
These updates simplify integration with network inventory systems and enhance visibility into large SNMP-managed environments.
Other Notable Improvements
- Reworked nProbe Source ID support for better flow exporters correlation
- Optimized Redis caching and flow statistics operations
- Stacked timeseries charts for clearer visualizations
- Support for up to 4K host pools
Fixes and Cleanups
This release includes dozens of bug fixes and UI refinements, improving stability and data accuracy across the board — from flow history export to traffic profile management and ClickHouse export reliability.
We’ve also removed obsolete code, unified exporter interfaces, and standardized MAC address formatting for consistency.
nEdge Enhancements
Our network edge solution, nEdge, gains new capabilities for dynamic blacklisting and policy enforcement:
- Dynamic blacklist with per-user/pool configuration
- Policy violation checks and flow blocking toggles
- Simplified shapers configuration
- Improved DHCP (now supporting both ISC and Kea servers)
- Enhanced traffic accounting and quotas management
These additions make nEdge more flexible and easier to manage in complex access control and bandwidth management environments.
Get ntopng 6.6
As always, you can install or update ntopng using your preferred package repository.
Detailed installation instructions are available on our download page.
We’d like to thank our community and enterprise users for their feedback, which continues to shape every ntopng release.
Stay tuned — as soon as will announce the date of a webinar where we will show you in details all the news of version 6.6.
