Summary
Koscom
hosting enterprise legacy
AS9526 (KOSCOM-AS-KR) is held by Koscom, the Korea Securities Computing Corporation — the financial-IT utility that supplies the technology backbone of Korea's capital markets. Koscom runs trading systems for the Korea Exchange, market-data distribution, and network and data-centre services for securities firms.
What it's used for
The routing evidence shows a service provider, not an end-site. RIS sees 44 IPv4 prefixes totalling 23,040 addresses, no IPv6, and 5 observed neighbours. The inventory splits cleanly in two. There is a core of large blocks — 114.31.112.0/21, 114.31.120.0/21, 211.255.192.0/21, 211.255.200.0/21, 39.125.128.0/21, plus /22s at 221.168.32.0, 103.244.108.0 and 128.134.148.0 — which is the operator's own infrastructure and data-centre space. Then there is a long tail of single /24s drawn from many unrelated parent ranges (123.141.x, 121.141.x, 118.37.x, 112.172.x, 1.254.x, 203.246.x, 211.169.x, 59.15.x, 211.175.x).
That tail is the signature of a shared-infrastructure operator: a /24 apiece, from whichever provider originally assigned it, announced from Koscom's AS because the customer's systems now sit in Koscom's facilities. With only five neighbours it is not a transit carrier — the customers are colocated and connected, not routed through.
Notable
- Koscom sits under the Ministry of Economy and Finance and the Korea Exchange, so it is closer to market infrastructure than to a commercial hosting company, even though its routing looks like one.
- Part of the legacy
128.134.0.0/16Korean class-B appears here as a/22; a/24from the same range is announced separately by AS9525, a brokerage — the same old block, split among the industry it was allocated to. - No IPv6 announced.

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 2026-10-18, 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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
