Hosting RIPE Content
Summary
CWCS
hosting business infrastructure
Eighty-four neighbours, and the reverse names give away who the customers are.
What it's used for
- A hosting and colocation provider. Eleven IPv4 prefixes and one IPv6
/32announced from the United Kingdom, nearly eight thousand addresses, across eighty-four observed BGP neighbours.
Notable
- One answering address returns an insurance firm's own domain, so a customer is identifiable from the address alone.
- Another names a router interface by port number, router number and site, which publishes part of the internal topology.
- A third belongs to a monitoring host on a fourth unrelated domain.
- One block's netname is simply its own prefix written with dashes, and its registrant is an unnamed private customer under a different hosting brand.
- Another block's abuse role is written in lower case as a single word that reads as an ordinary verb.
- Eighteen addresses were queried for reverse DNS and three returned a name.
Interesting
- Three answering addresses across three unrelated domains is what a hosting network looks like from outside: the addresses are the provider's, the names belong to whoever rents them.
- Eighty-four neighbours for eight thousand addresses is exceptional density. Hosting businesses buy reachability, and this one has bought a great deal of it.
- Netnames spanning many years and two corporate forms, one of them incorporated abroad, trace a company that kept acquiring space and eventually opened a second entity to hold it.

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: 442 networks and 1,779 prefixes, as published 2026-10-21. 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.
