About this network
AS9452 (KUNET-AS) is held by Korea University, one of the country's oldest and largest private research universities, based in Seongbuk-gu, Seoul. It is the campus network AS, announcing the university's own address space for students, staff, labs and public-facing services.
What it's used for
The routing evidence is about as clean as a campus network gets. RIS observes exactly one IPv4 prefix — 163.152.0.0/16, 65,536 addresses — and 1 BGP neighbour. No IPv6 is announced.
That single-prefix, single-upstream shape is the signature of a university that received a classful-era /16 and has never needed to fragment it: everything the institution runs fits inside one contiguous block, and it reaches the internet through the national research and education network rather than through commercial peering. Korea University's public services live inside this range — the korea.ac.kr web presence and the campus name servers all resolve into 163.152.0.0/16 — so the space is carrying the institution's own users and systems, not customers.
A 65k-address network with a single neighbour is definitively an end-user network. A transit or wholesale operator with the same address count would show dozens to hundreds of peers; Korea University shows one because it is a leaf of Korea's academic network, not a carrier.
Notable
- The whole allocation is a single legacy /16, unfragmented and unaggregated — no deaggregation into smaller announcements, which suggests a stable, well-consolidated campus routing policy.
- No IPv6 prefix is visible in RIS from this AS.
