Summary
Hoseo University
education university research legacy
AS9949 (HOSEO-AS) is held by Hoseo University, a private university in South Korea with campuses in Asan, Cheonan, Dangjin and Seoul. It is a campus network AS: the university originates its own address space so its sites can be multihomed across the Korean academic and commercial networks.
What it's used for
RIS sees 25 IPv4 prefixes carrying 13,312 addresses and no IPv6, reached through only 3 observed neighbours. Three upstreams and thirteen thousand addresses is a campus, not a service provider — enough space for laboratories, student networks, university-hosted services and dormitories across several sites, with none of the peering breadth a commercial network of the same size would show.
What makes the announcement list interesting is where the space comes from. The largest prefix, 210.119.104.0/21, sits inside KREONet — the Korea Research Environment Open Network run by KISTI — and 134.75.122.0/24 is likewise carved out of KREONet's 134.75.0.0/16. Others fall in 203.241.x, 210.110.x, 210.125.x and 220.x ranges long associated with Korean academic and public allocations. So the university does not hold one clean block; it announces a patchwork of sub-delegations handed down from the national research network and other academic pools, which is precisely how Korean campus networks are addressed.
Notable
- The registry shows the same space carrying route objects from KREONet's own AS1237 as well as from AS9949, which is normal for a university that originates delegated research-network space itself.
- The multi-campus structure explains the fragmentation: separate /22s and /24s per site rather than a single aggregate.
- No IPv6 announced, despite the research-network association where IPv6 is usually available.

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-14, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,772 prefixes, as published 2026-10-15. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
