How ProbeNet Provides Superior Data

Real-time measurements from a proprietary network of probes give IPinfo an accuracy advantage no aggregation-only approach can match.

Verified geolocation, not assumed

Backs every location estimate with active measurements from distributed points of presence, not just registry data.

Real-time IP stability tracking

Detects reassignment, geo drift, and fast-moving infrastructure with precise time-stamped fields like geo.last_changed.

Live privacy detection

Flags VPNs, proxies, and anonymized infrastructure using handshake analysis, port scans, and network behavior.

Continuous signal freshness

Ingests new measurements daily and re-verifies every IP weekly, ensuring constantly refreshed, verified datasets.

How ProbeNet Works

ProbeNet is an active measurement platform, constantly testing IPs from points of presence around the globe to generate real-world insights.

Measurement Process

  • Each PoP runs diagnostics like ping, traceroute, and protocol handshakes (e.g., TCP/UDP).
  • Traffic is routed through our enrichment pipeline where RTTs, headers, and behaviors are aggregated.
  • Outputs feed every IPinfo product, including geolocation, privacy detection, ASN context, and stability tracking.

Deployment Strategy

  • PoPs are strategically placed where RTTs are inconsistent, sparse, or noisy, including hard-to-measure regions like North Africa or the Pacific Islands.
  • We'll place probes in ASNs with just a /24 block (256 IPs) if latency patterns indicate instability or blind spots.
  • ProbeNet is maintained by a cross-functional team that:
    • Sources and negotiates servers
    • Identifies high-value ASN/region gaps
    • Automates provisioning and uptime

Ongoing Improvements

  • We maintain constant measurement with the clear goal of reducing RTT measurements across as many ASNs as possible.
  • Low RTT means ProbeNet sees the internet at extremely high resolution, enabling more accurate, fresh, and trustworthy IP data.
  • Latency benchmarks (Sept. 2025):
    • 1ms RTT for 44% of ASNs
    • 6ms RTT for 75%
    • 12ms RTT for 90%
  • In 2025, we improved performance on the highest-latency paths by 8%.

Achieving Data Accuracy Beyond ProbeNet

While ProbeNet is foundational to IPinfo's accuracy, it’s only one layer in a multi-source system designed to validate, enrich, and maintain our datasets. We combine active measurements with complementary methods to ensure both breadth and depth of coverage.

Registry + WHOIS Data

We ingest and normalize RIR records, taking care to flag outdated or vague entries while preserving useful attribution data.

Partner-Verified Signals

We collaborate with trusted network operators and commercial providers to ingest verified geo, privacy, and carrier information.

Behavioral & Heuristic Models

For non-responsive IPs, we infer likely characteristics using patterns across adjacent IPs, historical RTT baselines, ASN behavior, and infrastructure signatures.

IPinfo Confidence Layers

Each data point is tagged with provenance and freshness indicators (e.g., geo radius) to help customers gauge trustworthiness.

ProbeNet is not the only input we use, but it's the one that makes our claims verifiable. It's how we turn assumptions into measurable truth.
