AS9859 CCCC-AS ChungCheong University

AS9859 (CCCC-AS-KR) is held by Chung Cheong University (충청대학교), a private technical and vocational university in Cheongju, North Chungcheong Province. Founded in 1983, it teaches roughly five thousand students across engineering, design, health, business and applied-science programmes, with a strongly industry-oriented curriculum.

What it's used for

This is a campus network, and the routing evidence fits that read. RIS observes 27 IPv4 prefixes totalling 6,912 addresses, no IPv6, and only one BGP neighbour. A single upstream is the defining detail: whatever the university does with this space, it does not sell connectivity onward, and it has no peering role. It buys transit from one provider (Korean universities typically from a national research network or a commercial carrier) and announces its own space so its addresses stay portable.

Every prefix is an individual /24, and they come from at least six unrelated KRNIC ranges: 203.232.x, 203.234.x, 210.102.x, 210.181.x, 218.151.x and 220.67.x. That fragmentation is what a long-lived institution's address holdings look like after two decades of picking up a block here and a block there rather than receiving one aggregate. Seven thousand addresses across a campus of that size is generous by modern standards but unremarkable for a Korean university that acquired most of its space when IPv4 was still freely available: enough for lecture halls, labs, dormitories, administrative systems and departmental servers, all on public addresses.

Notable

• Single-homed despite holding 27 separate prefixes, which rules out any transit or peering role.
• No IPv6 is visible in the routing table.
