Spamhaus DROP
On Spamhaus ASN-DROP Spamhaus lists this entire
network (associated domain ddps.jp)
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 |
|---|---|---|

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 436 networks and 1,771 prefixes, as published 2026-10-13. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
