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.

2 DROP matches Announced space overlapping the DROP prefix list.

Announced	DROP entry	Record
124.68.168.0/24	124.68.0.0/16	SBL211387
172.111.240.0/24	172.111.128.0/17	SBL688605

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.

FBI IC3

1 IC3 indicators addresses in this network appear in FBI IC3 cybersecurity advisories.

Prefix	Advisory	Published
`45.154.12.132`	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.
