About this network
AS9317 (ITISNET-AS) is held by Inha University, a private research university in Incheon, South Korea. It is the university's campus network, and the routing evidence is textbook for one.
What it's used for
RIS sees 51 IPv4 prefixes carrying 65,536 addresses — a full /16 — with no IPv6 and only 3 observed BGP neighbours. That combination is diagnostic. A network with tens of thousands of addresses and three peers is not selling anything to anyone: it takes connectivity from a small number of Korean upstreams and originates only its own space. Campus networks look exactly like this, because the entire address block serves one organisation's staff, students, labs and services.
Every announced prefix falls inside 165.246.0.0/16. The prefix count is high only because the university deaggregates its own /16 into a long list of /22s, /23s and /24s alongside the covering route — a common practice on campus networks where different faculties, dormitories and machine rooms are announced separately for traffic engineering or multi-path reasons, rather than a sign of a fragmented or traded allocation. Public records show the university's own service infrastructure (nameservers and management hosts under inha.ac.kr) living inside the same /16.
Notable
- A single contiguous /16 for one campus is a legacy-era allocation; universities that joined the internet later got far less.
- Registry contacts point at the university's own network management office in Michuhol-gu, Incheon.
