Summary
Korea Research Institute of Standards and Science (KRISS)
KRISS-AS-KR is the Korea Research Institute of Standards and Science, the country's national metrology institute, based in the Daedeok research complex in Daejeon. Founded in 1975, it defines and maintains South Korea's measurement standards and represents the country under the Metre Convention.
What it's used for
Research and institutional connectivity for a national laboratory: calibration and standards work, physics and materials research, scientific data exchange with peer metrology institutes abroad, and the campus itself. The AS announces 2 IPv4 prefixes totalling 4,096 addresses and no IPv6 — two clean /21s, 203.254.160.0/21 and 210.98.16.0/21. Two tidy same-size blocks and nothing else is the fingerprint of a single institutional site that was allocated properly rather than accreting /24s over decades, and it is a notably larger per-site block than the Korean government agencies elsewhere in this range hold.
Notable
Carded as government: KRISS is a government-funded research institute under the National Research Council of Science and Technology, which reports to the Ministry of Science and ICT. It is a state body rather than a university, and it grants no degrees, though it hosts a graduate school in partnership with UST. The routing is consistent with an end-site: 4,096 addresses against one observed BGP neighbour, single-homed into what is almost certainly the national research network. It sells nothing; a carrier would show hundreds of adjacencies.
Interesting
KRISS keeps Korea Standard Time and broadcasts it nationally from the HLA station on 5 MHz. The handle's odd tail — SubDAEJONnetworks connected to backbone — is registry text describing the Daejeon campus links, not a separate organisation.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-14, 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: 442 networks and 1,773 prefixes, as published 2026-10-13. 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.
