Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-16, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Spamhaus DROP
On Spamhaus ASN-DROP Spamhaus lists this entire
network (associated domain sinoworldwidetrading.com)
as controlled by, or hijacked for, cybercrime. Many operators null-route
everything it originates.
1 DROP match Announced space overlapping the DROP prefix list.
| Announced | DROP entry | Record |
|---|---|---|
| 87.120.104.0/24 | 87.120.104.0/24 | SBL699922 |
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,783 prefixes, as published 2026-10-17. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
1 IC3 indicators addresses in this network appear in FBI IC3 cybersecurity advisories.
| Prefix | Advisory | Published |
|---|---|---|
85.11.187.8 | FortiBleed Operations Continue Targeting Exposed Systems Leading to Reports of Lockouts | 2026-10-06 |
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
