AS9753 DAU-AS Dong-A Universirty

AS9753 (DAU-AS-KR) belongs to Dong-A University, a private university in Busan, South Korea, spread across the Seunghak, Gudeok and Bumin campuses. The registry spells the name "Universirty" — a typo in the handle, not a different organisation.

What it's used for

This is a campus network. RIS shows 24 IPv4 prefixes covering 65,536 addresses and no IPv6 origin, announced to just 2 observed BGP neighbours. Every prefix is carved from a single legacy 168.115.0.0/16 — the university announces the full /16 aggregate and then a set of sixteen /20s, plus a handful of smaller /21s through /23s, all inside it. That deaggregation pattern is internal engineering made visible: a large campus splitting its address plan by building, faculty or campus site and originating each slice separately, most likely for traffic-engineering across its uplinks. Two neighbours is the giveaway that this is an end network. It has a genuinely large address holding but essentially no peering breadth: it consumes transit, typically from the Korean research and commercial networks, and provides none.

Notable

• A full /16 for a single university is an artefact of early class-B era allocation, not a measure of how many hosts are actually online. Korean universities were among the earliest institutional networks on the internet and hold address space out of all proportion to modern need.
• The whole announced footprint fits inside one /16, so there is no third-party or brokered space here; the inventory is entirely the institution's own.
• No IPv6 origin was observed, which is worth noting for a network of this size.
