Summary
Korea Institute of Machinery & Materials (KIMM)
research government education legacy
AS9568 (KIMM-AS-KR) is registered to the Korea Institute of Machinery & Materials (KIMM), a government-funded research institute in Daejeon that works on mechanical engineering, advanced manufacturing, nano-convergence systems, energy and environment systems, and machine reliability testing. It is an institutional network, not a service provider.
What it's used for
RIS shows 32 IPv4 prefixes totalling 8,192 addresses and no IPv6, and the whole allocation is one tidy block: every announced prefix falls inside 203.241.x.0/24, deaggregated into individual /24s. Only one BGP neighbour is observed. That combination is unambiguous. A network with a single upstream and a contiguous, self-contained address range is a leaf site consuming transit, almost certainly from Korea's national research and education network. Nothing transits it, it sells nothing, and it does not multi-home. The 8,192 addresses cover an institute campus: lab and test-rig networks, HPC and simulation resources, the public web and mail presence, and staff desktops. Splitting a contiguous range into 32 separate /24 announcements rather than a couple of aggregates is an old habit that usually reflects per-department or per-site routing policy inside the campus rather than any traffic-engineering need.
Notable
- KIMM is headquartered in Daejeon, Korea's principal research city, and operates regional centres in Daegu, Busan and Gimhae.
203.241.0.0/16-adjacent space is APNIC allocation used widely by Korean institutions; the AS holds a contiguous slice of it rather than fragments from many sources.- The single-neighbour, single-upstream shape means an outage at that one provider takes the institute off the internet, which is a normal trade-off for a research site that is not commercially exposed.

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 2026-10-15, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 442 networks and 1,781 prefixes, as published 2026-10-16. 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.
