Hosting ARIN
Summary
Coreix
hosting colocation dedicated cloud
The AS handle COREIX-UK-AS is held by Coreix Ltd.
What it's used for
- The address space carries hosting and colocation services, evidenced by reverse DNS entries such as
reverse.coreix.net,rdns.ezhostingserver.co.uk, andunassigned.servercity.co.uk. - With 32,000 IPv4 addresses announced across 23 prefixes and only 8 observed neighbours, the ratio indicates a hosting or access network rather than a transit provider.
Notable
- Registrants for the majority of prefixes are "Coreix Limited Admin" or "Coreix Ltd", consistent with the announcer, though one prefix (185.81.16.0/22) is registered to "AsYouNeed.com Ltd".
- The address inventory is subdivided into numerous smaller blocks, including multiple /22, /23, and /24 prefixes, alongside a large /18 block.

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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
