About this network
AS9868 (CUTH-AS-KR) is held by Daegu Catholic University (대구가톨릭대학교, also rendered Catholic University of Daegu), a private research university whose main Hyosung campus is in Gyeongsan, Gyeongbuk, next to Daegu. It enrolls upwards of twelve thousand students, runs a seminary and a medical school with an affiliated university hospital, and is the largest Catholic university in Korea.
What it's used for
RIS observes 13 IPv4 prefixes totalling 20,992 addresses, no IPv6, and three BGP neighbours. That is a substantial holding, and unlike most of the small enterprise networks in this ASN range it is genuinely aggregated: a 114.71.176.0/20, four separate /21s out of 203.250.32.0 upward, plus 116.90.216.0/21, 117.17.240.0/21 and 114.71.24.0/21. Whole /20s and /21s announced as single routes mean real allocations, not scraps of provider space picked up one /24 at a time.
Twenty thousand public addresses is consistent with a multi-campus university that hands routable addressing to lecture halls, laboratories, dormitories, administrative systems and a teaching hospital, which is a large network in its own right. Three upstreams gives the campus resilience, and is a common arrangement for Korean universities that connect both to a commercial carrier and to a national research and education network. Nothing here suggests transit, hosting resale, or any customer-facing role: three neighbours on twenty thousand addresses is a consumer of connectivity, not a seller of it.
Notable
- One of the larger address holdings in this ASN range, and one of the few that is properly aggregated rather than fragmented into /24s.
- Runs a medical school and university hospital, which typically accounts for a meaningful share of a campus network's address use.
- IPv4 only; no IPv6 is visible in the routing table.
