AS7624 JEONJU-AS jeonju university

JEONJU-AS is Jeonju University (jj.ac.kr), a private Christian university in Wansan-gu, Jeonju, in North Jeolla Province, South Korea. Founded in 1964, it gained full university status in 1983.

What it's used for

• Campus connectivity for students, faculty and departments. The main blocks are 202.31.224.0/19 — from the range KRNIC has long used for Korean academic institutions — plus 101.1.8.0/21 (registered as GEONJOO-NET), 112.140.152.0/21 and four /24s in 202.174.88.0/22.
• Addresses in the space geolocate to Jeonju and are attributed to the jj.ac.kr domain.

Notable

• Institutional address space, roughly 13,000 addresses. Traffic from it is students, staff and campus systems, not consumer broadband. There are no subscriber-style pools.
• The netname on the 101.1.8.0/21 block is GEONJOO-NET, an alternate romanisation of the city's name. Korean allocations often carry inconsistent transliterations of the same institution, so a name-only match can easily miss a block that genuinely belongs to the university.

Interesting

• Reverse DNS coverage is essentially absent across this ASN, as it is for many Korean campus networks. The KRNIC allocation records and the geolocation attribution to jj.ac.kr are what establish the holder here, not the DNS.
