CAUNET-AS-KR is the autonomous system for Chung-Ang University.

What it's used for

  • The space carries university infrastructure, identified by the netname CAU-NET-KR and registrant IRT-KRNIC-KR.
  • The AS announces 65536 IPv4 addresses across 1 prefix (165.194.0.0/16) with 1 observed neighbour, indicating a single-site institutional network rather than a transit or multi-site access provider.

Notable

  • The RDAP registrant IRT-KRNIC-KR aligns with the announcer, confirming the space is held by the university's own registry contact.
  • The address inventory consists of a single contiguous /16 block, typical for a large academic institution managing its own internal addressing.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-04, 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: 453 networks and 1,853 prefixes, as published 2026-11-05. 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.
