What it's used for
- The address space carries static IP endpoints, as indicated by reverse DNS records such as
static-ip-254-18-241-103.netonex.asiaandstatic-ip-128-254.25.103.rev.i4hk.com. - The AS announces 4,864 IPv4 addresses across 8 prefixes and 1 IPv6 prefix, with 22 observed neighbours, a ratio consistent with a regional network service provider.

Notable

- The address inventory is fragmented across various /22, /23, and /24 blocks in the 43.x, 103.x, 45.x, and 114.x ranges.

Reputation
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: 442 networks and 1,773 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 |
|---|---|---|
103.25.254.210 | Chinese Government-linked Cyber Threat Actors Combine Automated and Hands-on Hacking Tools to Steal Sensitive Data | 2026-10-08 |
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
