About this network

CUP-AS-KR is the Catholic University of Pusan (부산가톨릭대학교), a private university in Busan with a strong health-sciences and nursing focus.

What it's used for

• Campus connectivity: student and staff access, faculty and departmental servers, the library and learning-management systems, and the university's public web and mail presence.

Notable

The name alone would not settle the kind — University in a legal name is not proof of an education network, and plenty of commercial holders carry institutional-sounding titles. Here the reverse DNS confirms it directly: the one PTR in the sample resolves to spam.cup.ac.kr, an anti-spam mail gateway under Korea's .ac.kr academic domain, which only accredited educational institutions may use. That is first-party rDNS on the university's own space, so the network carries what the holder's name says it does.

The routing is a small, single-homed campus. RIS sees 2 announced IPv4 prefixes totalling 2,560 addresses (203.232.208.0/21 and 210.93.62.0/23), no IPv6, and only 1 observed neighbour. A single upstream is the honest signal that this is a customer network, not a provider: the university buys transit and announces its own space so it can keep its addresses if it changes carrier, but it sells connectivity to no one. A carrier would peer with hundreds of ASes.

Interesting

2,560 addresses is enough for a mid-sized campus of the era when every device got a public IP. Compare the very much larger Chonnam National University at AS10197, a national university with a full legacy /16.
