Summary
Kyungsung University
education university legacy
AS9691 (KYUNGSUNG-AS) is held by Kyungsung University (경성대학교), a private university in Nam-gu, Busan, South Korea. This is the university's campus network.
What it's used for
RIS sees 16 IPv4 prefixes carrying 14,848 addresses, no IPv6, and 1 observed BGP neighbour. Fifteen thousand addresses behind a single upstream is a straightforward campus profile: enough space for staff and student devices, labs, departmental servers and dormitory or wireless access across a single-city campus, with one transit relationship — almost certainly into a Korean carrier or the national research network — and no peering ambitions.
The inventory is visibly the product of decades of piecemeal assignment rather than one clean allocation. It spans four unrelated ranges: 210.110.160.0/20 and 210.110.176.0/22, 202.30.112.0/21 with a couple of small 202.30.32.0 blocks, a cluster in 117.16.92.0–117.17.128.0, and single /24s in 203.230.x and 203.234.x. A university that has been on the internet since the early Korean academic-networking era accumulates exactly this: a block per era, per building programme or per network provider, never renumbered because renumbering a campus is more expensive than announcing sixteen prefixes.
Reverse DNS confirms the holder rather than merely the handle: a sampled address in 202.30.32.0/23 resolves to sarang.kyungsung.ac.kr, a named host under the university's own ac.kr academic domain.
Notable
- The single BGP neighbour means this network does not multihome; its internet reachability rests on one upstream relationship.
- Despite the varied address ranges, everything traces back to one institution — the scatter is legacy assignment history, not a mixed-tenant estate.

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: 448 networks and 1,849 prefixes, as published 2026-10-29. 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.
