AS213876 ISEREBINAIRE3
Unclassified RIPE Educational/Research
Summary
LangYa Network
research ipv6 academic
ISEREBINAIRE3 is held by Qiyuan Chen, a doctoral student at Zhejiang University.
What it's used for
- The space carries two IPv6 prefixes:
2602:f92a:a462::/48and2a0f:1cc5:2000::/40. - With 0 IPv4 addresses and 4 observed neighbours, the inventory suggests a small-scale research or experimental network rather than a commercial access provider.
- Traffic from this AS is associated with academic research activities, specifically related to the LangYa Network project hosted at Zhejiang University.
Notable
- The registry holder is listed as LangYa-AS Qiyuan Chen, aligning with the individual researcher identity found in secondary sources.
- The address inventory consists solely of IPv6 space, with no IPv4 prefixes announced or in inventory.

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 2026-10-26, 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.
