Summary

Yukari Networks

China · AI-generated

research ipv6 academic

ZYK-AS is operated by Yukari Networks, an educational and research entity.

What it's used for

  • The address space consists exclusively of five IPv6 prefixes, including 2a0e:aa07:e280::/47 and 2a14:67c3:9990::/44.
  • With zero IPv4 addresses and five observed neighbours, the network functions as a small-scale research or academic endpoint rather than a transit or access provider.
  • Traffic from this AS represents research infrastructure and academic computing resources associated with the operator's educational mission.

Notable

  • The registry holder is listed as Zeng Yukai, while PeeringDB identifies the operator as Yukari Networks with an Educational/Research information type.
  • The address inventory is entirely IPv6, with no IPv4 allocation present in the announced inventory.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-26, 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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
