AS10053 AYTCNET-AS yeonsung University

AYTCNET-AS-KR is Yeonsung University, a private vocational college in Manan-gu, Anyang, Gyeonggi Province. AS10053 carries its campus network.

What it's used for

Ordinary campus connectivity: classrooms, labs, administration and student services for a school whose programmes lean heavily technical and applied — engineering, health sciences, culinary and design. The AS announces 20 IPv4 prefixes totalling 5,120 addresses and no IPv6. Every one of those prefixes is a /24, and they come from four unrelated ranges: 114.70.x, 203.230.x, 210.106.x and 210.181.x. That scattering is not a red flag here, it is a history lesson — a campus that grew its allocation a /24 at a time over decades, taking whatever its upstream had free, rather than receiving one clean block.

Notable

An education network. The decisive figure is two observed BGP neighbours against 5,120 addresses: an end-site that multihomes to a pair of upstreams and re-announces nothing for anyone else. A hosting provider at this size would show far more diverse peering and server-style naming; a carrier would show hundreds of adjacencies. Neither applies. The holder is a degree-granting institution and the space is its own.

Interesting

The handle preserves a name the school no longer uses. AYTC is Anyang Technical College, which is what Yeonsung was called from 1979; it passed through Anyang College and Anyang Science College before taking its present name in 2012. Do not confuse it with the separate [AS10071](https://asn.ipinfo.app/AS10071), Anyang University — a different institution in the same city.
