Summary
Redcentric Solutions
hosting business managed-services
FOURD-AS is operated by Redcentric Solutions Ltd, a UK managed service provider.
What it's used for
- The address space carries business and managed services traffic, evidenced by netnames like
UK-REDCENTRIC-20120330and reverse DNS entries such as79-99-66-0.4d-dc.comandmail.ptplatform.com. - With 34,304 IPv4 addresses announced across 38 prefixes and only 5 observed neighbours, the high address-to-neighbour ratio indicates a hosting or access network rather than a transit provider.
Notable
- Registrants largely align with the announcer, with most prefixes registered to Redcentric Solutions Ltd, though some blocks are registered to Liquid Web B.V. and Clear Connect Limited.
- The address inventory is a mix of /21, /22, and smaller blocks, including space originally allocated to other entities like Liquid Web B.V.

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 1,783 prefixes, as published 2026-10-20. 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.
