IPDR full form, meaning, and how IPDR analysis works — plus IPDR vs CDR analysis, IPDR records, and what an IPDR collector does, explained for investigators and telecom analysts.
IPDR full form: Internet Protocol Detail Record. It's a session log generated by an ISP or telecom operator that records the IP address, port, timestamps, and data volume for every internet session a subscriber makes — the internet equivalent of a phone call record.
IPDR (Internet Protocol Detail Record) is a log entry that an internet service provider or mobile network operator generates every time a subscriber opens, uses, or closes a data/internet session. Where a phone bill itemizes every call you made, an IPDR itemizes every internet session your device initiated — which IP address you were assigned, how long the session lasted, and how much data you used.
IPDRs exist because most subscribers share a small pool of public IP addresses through Network Address Translation (NAT). Without an IPDR, an investigator seeing "this IP address did X at this timestamp" has no way to trace it back to a real subscriber — the IPDR is the record that maps a public IP + port + timestamp combination back to the individual SIM or broadband connection that was using it.
IPDR records vary slightly by operator and by service type (broadband, mobile data, Wi-Fi hotspot), but a standard IPDR contains the following fields:
IPDR analysis (also called IPDR analytics) is the process of processing bulk IPDR files to answer investigative questions — who was using a given IP address at a given time, what apps or services a subscriber connected to, and how a suspect's online activity correlates with their physical location or phone calls. In practice, IPDR analysis is used for:
Because raw IPDR exports from telecom operators can run into millions of rows per day, IPDR analytics tools are used to ingest, index, and query this data quickly rather than manually filtering spreadsheets.
An IPDR collector is the network-side component — hardware or software — deployed by the ISP or telecom operator that captures IPDR events in real time as subscribers open and close internet sessions, timestamps them, and writes them to storage. The collector typically sits close to the operator's NAT/CGNAT gateway or Deep Packet Inspection (DPI) infrastructure, since that's where session and IP-allocation data is generated.
From the collector, IPDR data is either streamed to a lawful-interception system in near real time, or exported in bulk (daily/hourly files) for law enforcement and internal fraud/compliance teams to analyze. The collector's job ends at capture and storage — the actual investigative work happens in a downstream IPDR analysis platform.
CDR analysis — short for call data record analysis or call detail record analysis — is the equivalent process for voice and SMS metadata rather than internet sessions. A Call Detail Record logs who called whom, when, for how long, and via which cell tower, for every call and text message on a network.
CDR analysis is used to:
| CDR | IPDR | |
|---|---|---|
| Full form | Call Detail Record | Internet Protocol Detail Record |
| Captures | Voice calls and SMS metadata | Internet / data session metadata |
| Key fields | Caller, receiver, duration, tower ID | IP address, port, session time, data volume |
| Used for | Communication mapping, movement tracking | Online activity attribution, cybercrime tracing |
| Typical requester | Telecom operator (mobile/landline) | ISP or mobile data provider |
In most serious investigations, CDR and IPDR are analyzed together — a suspect's call activity from CDR is cross-referenced against their internet sessions from IPDR to build one unified timeline of physical and digital activity. This is exactly what the VedOps CDR/IPDR platform automates for law enforcement and telecom forensics teams.
IPDR stands for Internet Protocol Detail Record — a log of every internet session a subscriber makes, including IP address, port, timestamps, and data volume, generated by an ISP or telecom operator.
The full form of IPDR is Internet Protocol Detail Record, sometimes also called IP Detail Record.
IPDR analysis examines IP Detail Records to map internet sessions back to a subscriber, device, or timestamp — used to attribute online activity, detect VPN/proxy use, and correlate sessions with call records.
An IPDR collector is the network element deployed by an ISP or operator that captures, timestamps, and stores IP Detail Records before they're exported for analysis or lawful interception.
CDR analysis (call data record analysis) examines Call Detail Records — caller, receiver, duration, timestamp, tower ID — to map communication networks and reconstruct timelines.
CDR captures voice call and SMS metadata; IPDR captures internet/data session metadata such as IP address and data volume. Investigators often correlate both together.
