hosting business cloud security
NODE4-AS is operated by Node4 Limited.
What it's used for
- The address space carries business and cloud infrastructure, evidenced by netnames like
UK-NODE4-20040608andUK-NODE4-19930901registered to Node4 Limited. - With 60,672 IPv4 addresses across 109 prefixes and 103 observed neighbours, the inventory supports a hosting and managed services provider rather than a pure transit or residential access network.
Notable
- Registrants for the majority of prefixes align with the announcer, listing Node4 Limited and Node4 Network Role.
- One prefix, 193.203.240.0/21, is registered to The Samuel Oscar Company Limited under the netname
AVIATORS-NET, indicating leased or acquired space. - The inventory consists of numerous /22 and /21 blocks, reflecting a finely subdivided corporate estate typical of a UK-based IT solutions provider.

Classification and threat
Hosting Datacenter or cloud provider. Addresses are servers, not people.
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: 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 |
|---|---|---|
77.111.226.5 | 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.
