AS11892 PEARSON-NA
Unclassified ARIN
Summary
NCS Pearson Inc.
enterprise legacy
PEARSON-NA is held by NCS Pearson, Inc., the North American arm of the education publisher and assessment company Pearson. NCS is National Computer Systems, the scoring and testing business Pearson acquired, and the handle's NA is the region, not a network type.
What it's used for
Pearson's own service estate. RIS sees five IPv4 prefixes totalling 2,048 addresses, no IPv6, and three observed neighbours. Three neighbours is an end site: transit is bought, none is sold. The reverse DNS is the interesting part. Sampled names resolve to www.ebuzon.pearson.com.mx and to svc00376-us1-dev-1.lbaas.pearson.com, the second of which is a load-balancer-as-a-service hostname from an internal platform, complete with a numbered service ID and a dev environment tag. This is a corporate application estate, publicly routed so that customers and schools can reach it.
Notable
- Despite the parent company's business being education, this is not an education network in the sense the classification uses. No campus, no students, no residence halls sit behind it. It carries a commercial vendor's infrastructure, and the honest label is enterprise. Classifying by what the space carries rather than by what the holder sells is exactly the distinction that keeps a publisher out of the
educationbucket. - Every prefix is registered in ARIN to NCS Pearson Inc. itself, under network names that literally say
HOSTING. Self-registered space with first-party reverse DNS is a real operator running its own systems, with nothing leased in.

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.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-28, 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: 448 networks and 1,851 prefixes, as published 2026-10-29. 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.
