About this network
AS9970 (KUT-AS-KR) is held by the Korea University of Technology and Education (KOREATECH), a public university in Cheonan, South Chungcheong Province, established by the Ministry of Employment and Labor to train practical engineers and vocational-education specialists. The KUT handle is the university's older initialism.
What it's used for
RIS sees 11 announced IPv4 prefixes totalling 12,800 addresses, no IPv6, and 2 observed BGP neighbours. A single /19 (220.68.64.0/19) supplies most of the space — 8,192 addresses in one aggregate — with the remainder split across /22s, /23s and /24s in 210.119, 210.181, 203.255 and 218.150.
That mix of one large, clean aggregate plus a tail of fragments is the classic campus profile: an original block sized for the whole site, then a series of smaller top-ups collected over the years. Twelve-and-a-half thousand routable addresses for a mid-size engineering university reflects the Korean academic norm of putting labs, teaching machines and dormitory ports directly on public IPv4 rather than behind carrier-grade NAT — KOREATECH houses close to 70% of its students on campus, and residence-hall connectivity alone accounts for a meaningful share of an allocation like this.
Two upstreams and no peering confirm the role: this network consumes transit and originates only its own space.
Notable
- KOREATECH's curriculum is half practical, with 24-hour lab access and an industry-placement model, so a substantial part of this address space serves teaching and research labs rather than office desktops.
- The 220.68/16 range here is shared with other Korean university networks in this ASN range.
- No IPv6 is announced.
