Network type: education

AS9568 announces 4 IPv4 prefixes covering 8,192 addresses and 0 IPv6 prefixes.

About this network

AS9568 (KIMM-AS-KR) is registered to the Korea Institute of Machinery & Materials (KIMM), a government-funded research institute in Daejeon that works on mechanical engineering, advanced manufacturing, nano-convergence systems, energy and environment systems, and machine reliability testing. It is an institutional network, not a service provider.

What it's used for

RIS shows 32 IPv4 prefixes totalling 8,192 addresses and no IPv6, and the whole allocation is one tidy block: every announced prefix falls inside 203.241.x.0/24, deaggregated into individual /24s. Only one BGP neighbour is observed. That combination is unambiguous. A network with a single upstream and a contiguous, self-contained address range is a leaf site consuming transit, almost certainly from Korea's national research and education network. Nothing transits it, it sells nothing, and it does not multi-home. The 8,192 addresses cover an institute campus: lab and test-rig networks, HPC and simulation resources, the public web and mail presence, and staff desktops. Splitting a contiguous range into 32 separate /24 announcements rather than a couple of aggregates is an old habit that usually reflects per-department or per-site routing policy inside the campus rather than any traffic-engineering need.

Notable

• KIMM is headquartered in Daejeon, Korea's principal research city, and operates regional centres in Daegu, Busan and Gimhae.
• 203.241.0.0/16-adjacent space is APNIC allocation used widely by Korean institutions; the AS holds a contiguous slice of it rather than fragments from many sources.
• The single-neighbour, single-upstream shape means an outage at that one provider takes the institute off the internet, which is a normal trade-off for a research site that is not commercially exposed.
