Unclassified AFRINIC
Summary
SKH Network
ipv6 research china
WMJ-AS is held by Mingjie Wu.
What it's used for
- The address space consists entirely of six IPv6 prefixes, including
2a13:a5c7:3301::/48and2a13:a5c7:3306::/47, with no announced IPv4 addresses. - The network maintains five observed neighbours, a ratio consistent with a small-scale access or research network rather than a transit provider.
- Traffic from this AS is associated with SKH Network, an organization linked to academic and research activities in China.
Notable
- The registry holder is listed as Mingjie Wu, while PeeringDB identifies the operator as SKH Network.
- The address inventory is finely subdivided into multiple /48 blocks, indicating internal segmentation for specific sites or projects.

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: 445 networks and 1,817 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.
