AS9572 HUFSNET-AS Hankuk University of Foreign Studies Computer Center

AS9572 (HUFSNET-AS) is the campus network of the Hankuk University of Foreign Studies (HUFS), a private research university in Seoul best known for its language and international-studies faculties. The registry lists the holder as the university's Computer Center, the in-house team that runs the network.

What it's used for

RIS shows 7 IPv4 prefixes carrying 16,128 addresses, no IPv6, and one BGP neighbour. Reverse DNS confirms the holder directly rather than merely hinting at it: 203.232.224.5 resolves to webmail.hufs.ac.kr, so the space is carrying the university's own services under its own ac.kr academic domain. The prefix list is built around three /20s (203.253.64.0/20, 203.232.224.0/20, 203.253.80.0/20) plus smaller fragments, and 16,128 addresses is a generous public allocation for a university of this size. That is characteristic of an institution that took its space early, when handing every campus machine a routable address was still normal, and never had to retreat behind carrier-grade NAT. The single upstream marks it as a leaf network: it consumes transit, presumably via the Korean research and education networking arrangements, and carries no traffic for anyone else.

Notable

• HUFS runs two campuses, the Seoul Campus in Imun-dong and the Global Campus in Yongin, and the split address blocks are consistent with serving both sites from one AS.
• The university teaches dozens of foreign languages and is one of Korea's leading institutions in humanities and social sciences.
• A single BGP neighbour means no redundancy at the routing layer, which is a common and generally accepted posture for a campus that is not commercially exposed.
