About this network
AS9686 (SKKUNET-AS) is held by Sungkyunkwan University (SKKU), a private research university in South Korea with a humanities and social sciences campus in Seoul and a Natural Sciences campus in Suwon. This is the university's own campus network.
What it's used for
RIS sees 8 IPv4 prefixes carrying 73,728 addresses, no IPv6, and 4 observed BGP neighbours. That is a large address holding for a single institution — roughly 72,000 usable addresses — but reached through only a handful of BGP adjacencies, which is exactly the university profile: a big legacy allocation supporting a whole campus estate, connected upward to the national research network and commercial carriers rather than peering widely.
The structure of the inventory reflects two eras of assignment. A pair of adjacent /17s (115.145.0.0/17 and 115.145.128.0/17) accounts for the great majority of the addresses and looks like a later, contiguous allocation, while a cluster of smaller blocks in 203.252.32.0–203.252.61.0 (a /20, a /21, two /22s and two /24s) is the older, piecemeal campus space. A network of that size carries the usual university population: faculty and staff desktops, lab and research systems, departmental servers, dormitory and wireless access for students, and the institution's public web and mail presence. One sampled address returned no PTRs.
Notable
- Address volume alone would put this AS in ISP territory by size, but the four-neighbour footprint marks it as an end-site campus network that consumes transit rather than provides it.
- The two /17s carrying most of the space mean a large share of the university's hosts sit in one contiguous range, which makes campus-wide geolocation of SKKU traffic unusually clean.
