Summary

Korea Meteorological Administration

South Korea · AI-generated

KMA-AS-KR is the Korea Meteorological Administration, the national weather service. It runs South Korea's forecasting, observation and warning systems, its supercomputing centre, and the COMS/GEO-KOMPSAT weather-satellite ground segment. AS10063 is its network.

What it's used for

Weather data in and out. The AS announces 10 IPv4 prefixes totalling 2,560 addresses and no IPv6 — nine consecutive-ish /24s from 203.247.66.0 through 203.247.101.0 plus one from 210.107.255.0. The sampled reverse DNS is decisive: 203.247.66.133 resolves to missdp.kma.go.kr, first-party naming inside the agency's own .go.kr zone. .go.kr is the Korean government's restricted second-level domain, so this is not merely a plausible attribution — it is the holder identifying itself. A national met service is a heavy data exporter: model output, radar and satellite imagery, and observation feeds exchanged with the WMO's Global Telecommunication System and with peer agencies abroad.

Notable

A government network, plainly. The routing shape supports the reading rather than contradicting it: 2,560 addresses against four observed BGP neighbours describes an agency multihoming across a few upstreams for resilience — sensible for a body that must publish typhoon and heavy-rain warnings when other infrastructure is under stress. It sells no connectivity; a carrier would show hundreds of adjacencies.

Interesting

Four neighbours is on the high side for an end-site of this size in this range, where most Korean agencies show two. That is consistent with an operator whose availability requirements are genuinely public-safety grade rather than merely administrative.

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 1,783 prefixes, as published 2026-10-17. 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.
