Summary
Daegu University
education university korea
AS18401 is operated by Daegu University.
What it's used for
- The address space carries university network traffic, with netnames
TGUNET-KRandKREN-KRindicating allocation through the Korean Research and Education Network. - The AS announces 27,648 IPv4 addresses across 7 prefixes while maintaining only 2 observed neighbours, a ratio characteristic of an access or eyeball network rather than a transit provider.
Notable
- Registrants for all announced prefixes are
IRT-KRNIC-KR, which aligns with the Korean National Internet Center managing allocations for domestic educational institutions. - The inventory consists of a mix of /18, /20, /21, /23, and /24 blocks, including two /24s in the 160.30.0.0/16 range, suggesting a segmented internal corporate or campus estate.

Internet exchanges
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 2026-10-13, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
