Unclassified ARIN
Summary
Esri (Environmental Systems Research Institute)
ESRI is the network of the Environmental Systems Research Institute, the Redlands, California software company behind ArcGIS. Despite the research-sounding legal name, Esri is a privately held commercial software vendor, not an academic institute.
What it's used for
RIS observes 17 IPv4 prefixes carrying 4,352 addresses and no IPv6. Every announced prefix is a /24 from a single contiguous legacy range, 198.102.32.0 through 198.102.63.0 — effectively a /19 that Esri deaggregates into individual /24s and announces piecemeal. The sampled reverse DNS lands squarely in the holder's own domain: raytest4.esri.com, a first-party host name.
Deaggregating a /19 into 17 separate /24 announcements is a traffic-engineering choice, not a sign of a fragmented estate. It lets a company steer specific subnets to specific upstreams or sites.
Notable
The kind is enterprise/business. The name is exactly the trap this classification usually falls into: "Research Institute" reads like education, and it is not. Esri is a for-profit vendor, and the network carries its corporate offices, engineering labs and product infrastructure.
The routing agrees. Eight observed BGP neighbours against 4,352 addresses is a well-connected enterprise buying transit and peering a little, nothing like the hundreds a carrier would show. And 4,352 addresses is far too small to be the company's public cloud footprint. Esri's large-scale ArcGIS Online service runs on commercial cloud platforms, not here.

Interconnection
Peering at a glance
Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
7 upstream, 0 downstream and 7 adjacent networks observed; most-used upstreams first.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-07, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 454 networks and 1,852 prefixes, as published 2026-11-08. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
