Summary
Claranet
hosting enterprise legacy
CLARANET-AS is Claranet Limited, a London-headquartered managed-services group operating across the UK, France, Germany, Spain, Portugal, Italy, the Benelux and beyond. It started in the 1990s as an internet service provider and is now primarily a managed hosting, cloud and network provider for businesses.
What it's used for
- Managed hosting and cloud workloads run on behalf of corporate customers, plus business connectivity. Customer addresses resolve under per-country subdomains such as
host-IP-ADDR.customer.es.clara.net, and the operator's own infrastructure sits undernoc.clara.net. - Roughly 900,000 IPv4 addresses across around 80 prefixes, with a broad IPv6 footprint and a very large peering fan-out for a non-carrier.
Notable
- This is not eyeball space. There are no subscriber pools in the reverse DNS. An address here is far more likely to be a hosted server or a company office than a home connection, despite Claranet's ISP origins.
- Many prefixes carry the reverse DNS of acquired ISPs rather than Claranet's own domain, and a good deal of the range answers
unallocatedor has no rDNS at all. Claranet grew largely by buying up national providers, and the routing table still shows the seams. - Customer domains appear directly in the rDNS, which means some prefixes will geolocate and attribute to the customer, not to Claranet.
Interesting
- The
clara.netdomain is one of the older commercial names still in daily use on the European internet, dating from the company's dial-up era and surviving every rebrand since.

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 1,775 prefixes, as published 2026-10-11. 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.
