UNIVNET is the AS handle for Univnet, the Advanced Software Technology and Management Research Institute of Kyoto.

What it's used for

  • The address space is registered under netnames KYSA-NET and KYSA2-NET-CIDR-BLK-JP, indicating a dedicated network for the Kyoto University research institute.
  • The AS announces 4,352 IPv4 addresses across 2 prefixes with only 1 observed neighbour, a ratio consistent with a small, self-contained research or institutional network rather than a transit provider.
  • Traffic from this AS originates from the Advanced Software Technology and Management Research Institute, a research body associated with Kyoto University, carrying internal research and academic data.

Notable

  • Registrants for both prefixes are listed as IRT-JPNIC-JP and Japan Network Information Center, which aligns with the Japanese registry holder Univnet - Advanced Software Technology and Management Research Institute of KYOTO.
  • The inventory consists of one /20 block (163.208.176.0/20) and one /24 block (192.50.154.0/24), with no IPv6 prefixes announced.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-29, 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: 448 networks and 1,849 prefixes, as published 2026-10-29. 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.
