Trisul IPDR DoT Compliance Use Cases for ISPs
Simplify IPDR compliance and subscriber investigations across ISP networks.
Trisul IPDR enables ISPs to search IPDR, NAT, and AAA records from a single interface for subscriber lookup, historical investigations, NAT correlation, and DoT-compliant reporting.
Subscriber Lookup & Investigations
How can an ISP identify the subscriber behind an IP address?
Identifying the subscriber behind an IP address requires correlating IPDR records, NAT translations, and AAA records. Trisul IPDR enables ISPs to search historical IPDR, NAT, and AAA data from a single interface to accurately identify subscribers, investigate historical activity, and respond quickly to compliance and LEA requests.
- Search historical IPDR records by IP address, timestamp, and port
- Correlate NAT Syslog records with AAA and RADIUS data
- Export investigation results in DoT-compliant formats
Benefit: Accurately identify subscribers behind IP addresses and maintain complete audit trails for compliance and LEA requests.
Parallel IP Investigations
How can ISPs search multiple IP addresses at once?
ISPs often need to investigate hundreds or thousands of IP addresses simultaneously for abuse investigations, LEA requests, and compliance audits. Trisul IPDR enables ISPs to search multiple IP addresses in parallel, correlate IPDR, NAT, and AAA records, and generate reports from a single interface.
- Upload and search multiple IP addresses simultaneously
- Execute parallel search jobs across historical records
- Generate bulk reports in DoT-compliant formats
Benefit: Search thousands of IP addresses simultaneously and reduce the manual effort required for large-scale investigations.
CGNAT & NAT Log Correlation
How do ISPs correlate NAT logs with subscriber identities?
Identifying subscribers behind CGNAT IP addresses requires visibility into NAT translations, IPDR records, and subscriber sessions. Trisul IPDR brings these records together in a single interface, enabling ISPs to quickly identify subscribers and investigate historical activity.
- Ingest NAT Syslog and IPDR flow records
- Correlate NAT translations with subscriber identities
- Search historical NAT sessions and subscriber activity
Benefit: Accurately identify subscribers behind shared public IP addresses and simplify investigations across CGNAT deployments.
Audit Subscriber Activity & DoT-Compliant Reporting
How can ISPs audit subscriber activity and generate DoT-compliant reports?
ISPs need to investigate historical subscriber activity for regulatory audits, LEA requests, abuse investigations, and internal compliance reviews. Trisul IPDR enables operators to search historical IPDR, NAT, and AAA records from a single interface and automatically generate reports in DoT-prescribed formats.
- Generate reports in DoT-prescribed formats
- Export investigation results as Excel files
- Transfer reports securely through SFTP
Benefit: Automate regulatory reporting and generate accurate DoT-compliant IPDR reports with minimal manual effort.
Multi-Vendor IPDR Collection
How do ISPs collect IPDR logs from Cisco, Juniper, and CGNAT devices?
ISP networks often contain routers, CGNAT devices, and authentication systems from multiple vendors, each generating records in different formats. Trisul IPDR collects and normalizes IPDR records from NetFlow, IPFIX, Syslog, NAT Syslog, and AAA sources, providing a unified view of subscriber and network activity.
- Collect records from NetFlow, IPFIX, and Syslog sources
- Integrate NAT Syslog and AAA / RADIUS logs
- Normalize records from multiple vendors into a unified database
Benefit: Consolidate IPDR, NAT, and AAA records from multiple vendors into a single repository for simplified management and reporting.

| Deployment | Custom development and maintenance | Plug-and-play |
IPDR DoT Compliance Frequently Asked Questions
What is an IPDR and why do ISPs need it?
An Internet Protocol Detail Record (IPDR) contains information about network activity such as source and destination IP addresses, ports, protocols, timestamps, and subscriber details. ISPs use IPDR records to comply with Department of Telecommunications (DoT) regulations, investigate abuse incidents, respond to Law Enforcement Agency (LEA) requests, and maintain historical records of subscriber activity.
Trisul IPDR collects, stores, and retrieves IPDR records from multiple sources including NetFlow, IPFIX, NAT Syslog, and AAA logs.
What are the DoT requirements for IPDR retention?
The Department of Telecommunications (DoT) requires ISPs to maintain IPDR records, NAT logs, and subscriber mappings for prescribed retention periods and provide information when requested by authorized agencies.
Trisul IPDR helps ISPs retain and retrieve historical records efficiently through compressed storage, indexed searches, and configurable retention policies.
Why do many in-house IPDR compliance solutions become difficult to maintain?
As ISP networks grow, maintaining custom IPDR scripts and databases can become increasingly complex due to evolving flow formats, CGNAT deployments, retention requirements, and changing reporting mandates. In-house solutions often require significant effort to maintain parsers, correlation logic, storage infrastructure, and reporting workflows across multiple systems.
Dedicated IPDR platforms provide a plug-and-play alternative with built-in support for IPDR, NAT, and AAA collection, automated DoT-compliant reporting, and AI-assisted investigations. By eliminating custom tooling and manual reporting workflows, ISPs can focus on operations and investigations rather than maintaining compliance infrastructure.
Does Trisul IPDR require changes to my existing network infrastructure?
No.
Trisul IPDR is designed to integrate with existing ISP networks and can ingest records from routers, firewalls, CGNAT devices, and authentication systems without requiring infrastructure changes.
The platform supports NetFlow, IPFIX, Syslog, NAT Syslog, AAA, and raw packet sources.
Which network devices and log sources are supported?
Trisul IPDR can ingest records from a wide range of network devices and systems including:
- Routers exporting NetFlow
- Devices exporting IPFIX
- CGNAT devices generating NAT Syslog
- AAA and RADIUS servers
- Raw packet capture sources
This enables deployment in heterogeneous, multi-vendor ISP environments.
Can Trisul IPDR be deployed on-premises or in the cloud?
Yes.
Trisul IPDR supports on-premises deployments on customer infrastructure as well as cloud-based deployments.
ISPs can choose the deployment model that best suits their operational, security, and regulatory requirements.
How does Trisul IPDR store large volumes of IPDR data efficiently?
IPDR systems process millions of records every day, making storage efficiency a key consideration.
Trisul IPDR uses compressed storage and flow deduplication techniques to reduce storage requirements while maintaining fast search performance across historical datasets.
Is Trisul IPDR AI Assistant safe to use for compliance investigations?
Yes.
Trisul IPDR AI Assistant operates only at the workflow layer and does not have direct access to IPDR, NAT, or subscriber logs. It helps users navigate the platform and retrieve information through controlled queries while the underlying compliance data remains protected by Trisul’s existing access controls.
This allows ISPs to benefit from AI-assisted workflows without exposing sensitive compliance data.
Is Trisul IPDR future-ready if DoT compliance requirements change?
Yes.
Trisul IPDR is designed to evolve with changing regulatory and operational requirements. The platform supports multiple data sources including NetFlow, IPFIX, NAT Syslog, AAA, and raw packet capture, allowing new record types and workflows to be incorporated as requirements evolve.
Its modular architecture enables updates to report formats, search workflows, and data correlation logic without requiring a complete redesign of the deployment. This helps ISPs adapt to changing DoT guidelines while continuing to use their existing infrastructure and historical data.
Whether the changes involve new reporting formats, additional subscriber information, or evolving logging requirements, Trisul IPDR is built to grow alongside regulatory needs.
