AS9459 ASKONKUK Konkuk University

AS9459 (ASKONKUK) is held by Konkuk University (건국대학교), a private research university with its main campus in Gwangjin-gu, Seoul and a second campus in Chungju. This is the university's own campus network AS, carrying students, faculty, research groups and the institution's public services.

What it's used for

RIS observes 52 IPv4 prefixes totalling 23,552 addresses and just 2 BGP neighbours. No IPv6 is announced.

Two upstreams on 23,552 addresses is decisive: this is an end-site, not a carrier. A wholesale network with this much space would peer with dozens or hundreds of ASes; a university peers with its national research-and-education network and perhaps one commercial backup, which is what two neighbours looks like.

The prefix list tells the campus story. The anchor is 203.252.128.0/19 with a /21 and several /23s alongside it, and then the announcements fan out across four other unrelated ranges — 210.119.x, 117.16.x, 114.70.x, 113.198.x and a 103.218.160.0/22-sized cluster — mostly as individual /24s. That pattern is what a long-lived institution accumulates: an original classful-era allocation, then extra blocks obtained piecemeal over the years as departments, dormitories, a second campus and research facilities came online. Fifty-two announcements for 23k addresses means heavy deaggregation, which universities commonly do to route different faculties, buildings or campuses independently.

Notable

• The address space spans at least five distinct Korean allocations rather than one contiguous block, consistent with growth over time rather than a single assignment.
• No IPv6 is visible in RIS from this AS, which is notable for a research university in a country with otherwise strong IPv6 deployment.
