AS10197 — CNU-AS-KR Chonnam National University
Network type: education
AS10197 announces 1 IPv4 prefixes covering 65,536 addresses and 1 IPv6 prefixes.
About this network
CNU-AS-KR is Chonnam National University, a large national research university in Gwangju with additional campuses at Yeosu and Hwasun.
What it's used for
- Campus networking for a national university: faculty and administrative systems, research groups and their servers, libraries, hospital and dormitory access, plus the links out to Korea's research-and-education backbone and to commercial transit.
Notable
This is a textbook education network, and the address footprint is what makes that legible. RIS sees 11 announced IPv4 prefixes totalling 65,536 addresses — a full legacy /16 at 168.131.0.0/16, with ten more-specific /24s deaggregated out of it — plus 1 IPv6 prefix and 4 observed neighbours.
The 168.131.0.0/16 block is the giveaway. A whole class-B assigned to one institution is a pre-CIDR artefact of the era when universities were the internet's early adopters and address space was handed out by the class; no commercial network founded today would be given one. The ten deaggregated /24s alongside the covering /16 are ordinary traffic engineering — steering individual campus subnets down different upstreams — not a sign of fragmentation. Four neighbours is a multi-homed customer edge, not a carrier.
Interesting
The IPv6 announcement is 2402:1::/36, one of the lowest-numbered blocks in the whole 2402::/16 APNIC range — an early-adopter allocation from when Korean universities were among the first networks anywhere to deploy IPv6 in production. The Catholic University of Pusan sits one number later at AS10198.
