Summary

Doosan Enerbility

South Korea · AI-generated

enterprise manufacturing korea

DOOSANHEAVY-AS-KR belongs to Doosan Enerbility (formerly Doosan Heavy Industries & Construction), the Changwon-based power-plant and heavy-equipment manufacturer that builds turbines, generators, nuclear steam-supply systems and desalination plants.

What it's used for

  • Corporate connectivity for a large industrial group: headquarters and the Changwon works, engineering and CAD/PLM systems, supplier and project extranets, mail and VPN concentrators for staff and partners on overseas construction sites.

Notable

This is an enterprise network with an unusually generous allocation. RIS sees exactly 1 announced IPv4 prefix — 203.226.64.0/18, 16,384 addresses — no IPv6, and only 2 observed neighbours. The address count on its own could be mistaken for an ISP; the neighbour count rules that out. Two peers is a dual-homed corporate edge, whereas any network selling transit or serving eyeballs peers with tens to hundreds of others. A single, clean /18 announced as one aggregate is also a registry-assignment signature — one block handed to one organisation — rather than the scattered accretion you see in a reseller.

The /18 is a relic of an era when a Korean industrial conglomerate could ask KRNIC for a large block and get it. Doosan's internal estate (plant networks, engineering workstations, site offices) is numbered inside it, but very little of it needs to be globally reachable, which is why the AS shows a big prefix and an otherwise unremarkable edge.

Interesting

The handle still says DoosanHeavy: the company renamed itself Doosan Enerbility in 2022 to signal a pivot from coal to gas turbines, nuclear and wind, but the AS handle — like most handles — outlived the rebrand.

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 2026-11-03. 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.
