Summary
Rackspace (London)
cloud hosting managed-hosting
A Rackspace Autonomous System covering its UK/London operations (RACKSPACE-LON). Rackspace is a long-established managed hosting and multi-cloud company; this ASN announces prefixes for its European datacenter and managed-hosting customers.
What it's used for
- Managed dedicated hosting, private cloud, and colocation for Rackspace's UK/European customers.
Notable
- An IP here identifies Rackspace as the host, not the operator of the service running on it.
- Rackspace operates several regional ASNs; this is the London/UK block, sibling to its US and other Autonomous Systems.
Interesting
- Rackspace pioneered the "Fanatical Support" managed-hosting model and was a co-founder of the OpenStack cloud project with NASA in 2010.

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: 440 networks and 1,773 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
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.
