About this network
AS9523 (MOKWON-AS-KR) is held by Mokwon University, a private Methodist-affiliated university in Daejeon, South Korea. It is the campus network for a single institution of roughly 13,000 students.
What it's used for
A university campus AS. RIS sees 14 IPv4 prefixes covering 11,520 addresses, no IPv6, and 2 observed neighbours. The address count is the interesting number: 11,520 routed IPv4 addresses for a mid-size university is generous by modern standards, and it reflects the era in which Korean universities were allocated space — when a campus expected a public address for every machine rather than NAT behind a handful of blocks.
The inventory is fragmented in a way that reads as accretion over time, not as a curated portfolio: three /21s carrying the bulk of the space (220.68.200.0/21, 203.230.144.0/21, 203.230.136.0/21), then progressively smaller /22s, /23s and /24s from unrelated ranges — 203.249.x, 220.81.x, 114.70.x, 175.126.x, 1.245.x. Blocks from that many different parents mean assignments picked up in several rounds, from more than one source, over many years.
Two neighbours and no peering: the university buys transit and, as is standard for Korean higher education, sits behind national research/education connectivity rather than interconnecting on its own account.
Notable
- Mokwon is best known for its theology, fine-arts, music and education colleges; the network exists to serve that single campus, with no customer cone.
- 14 prefixes for one campus is a lot of separate announcements — the routing table cost of a long accretion history rather than any traffic-engineering intent.
