AS9767 DONGBUIT-AS-KR-KR - DB Inc.
Unclassified APNIC
Summary
DB Inc. (formerly Dongbu)
enterprise hosting legacy
AS9767 (DONGBUIT-AS-KR) is held by DB Inc., the IT services company of South Korea's DB Group. It was Dongbu Inc. until an October 2017 rename, which is where the DONGBUIT handle comes from. The business is systems integration and IT outsourcing — application and infrastructure operations, disaster recovery and security services, an integrated data centre, and cloud — sold mainly into finance, the public sector, manufacturing, construction and logistics, alongside the group's own affiliates.
What it's used for
The routing evidence matches an IT outsourcer running a data centre rather than an ISP running an access network. RIS shows 10,496 IPv4 addresses across 41 prefixes, and the arithmetic is exact: every single announcement is a /24. They cluster heavily in 210.127.x with smaller groups in 210.101.x, 210.126.x, 210.108.x and 211.60.x. A wall of same-sized /24s, no aggregates above them, is what you get when address space is handed out one block per hosted customer or per managed environment — which is precisely what an SI/ITO provider does for the clients whose systems it operates.
Only two observed BGP neighbours back this up. A network with thousands of neighbours on 10k addresses would be a transit carrier; two upstreams and no peering fabric means this AS exists to keep a managed data centre reachable, not to move other people's traffic.
Notable
- DB Inc. also runs non-IT lines (chemical and steel trading, HR services), so the corporate entity is broader than the network. The AS itself is purely the IT services and data-centre side.
- No IPv6 is announced.

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 2026-11-06, 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 1,854 prefixes, as published 2026-11-06. 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.
