AS213903 ZLY-AS
Unclassified APNIC Educational/Research
Summary
Liuyang Zhang
research academic ipv6
ZLY-AS is held by Liuyang Zhang.
What it's used for
- The space carries a single IPv6 prefix,
2406:840:fef0::/47, with no IPv4 addresses announced. - The inventory consists of 1 IPv6 prefix against 1 observed neighbour, indicating a small-scale research or academic network rather than a transit or access provider.
- Traffic from this AS is associated with academic research activities, specifically within the geology and earth sciences domain at China University of Geosciences.
Notable
- The registry holder is Liuyang Zhang, a researcher at China University of Geosciences, consistent with the PeeringDB classification of Educational/Research.
- The address inventory is minimal, comprising only one IPv6 block, which is typical for individual or small-group research networks in China.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
1 upstream, 0 downstream and 1 adjacent networks observed; most-used upstreams first.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-31, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Reputation
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: 447 networks and 1,845 prefixes, as published 2026-10-31. 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.
