Unclassified Spamhaus ASN-DROP ARIN
Summary
ISNX
business transit legacy
ISNX is the AS handle for ISNX LLC.
What it's used for
- The address space carries a mix of legacy ISP and corporate blocks, with netnames including
VOYAGER-WI-2000,VOYAGER98,NBLnet,TTTNET,LAIDLAWPSG,MTCL-HK, andAPNIC-AP. - The AS announces 9984 IPv4 addresses across 10 prefixes and maintains 3 observed neighbours, a ratio that suggests a transit or peering role rather than a large access network.
Notable
- Registrants include CoreComm Internet Services Inc, Laidlaw Passenger Services Group, TT&T Co., Ltd., Mega Target Communication Limited, and APNIC Hostmaster, indicating the space was likely acquired from or leased from multiple former owners.
- The inventory is fragmented, containing blocks from various historical operators such as Voyager and NBLnet, which do not fit a single unified corporate estate.

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.

Spamhaus DROP
On Spamhaus ASN-DROP Spamhaus lists this entire
network (associated domain cloudie.hk)
as controlled by, or hijacked for, cybercrime. Many operators null-route
everything it originates.
2 DROP matches Announced space overlapping the DROP prefix list.
| Announced | DROP entry | Record |
|---|---|---|
| 58.147.8.0/22 | 58.147.0.0/17 | SBL695321 |
| 204.187.192.0/22 | 204.187.192.0/19 | SBL641809 |
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.
