Summary
Colt Technology Services
colo datacenter transit
One of the Autonomous Systems of Colt Technology Services (COLT), a London-headquartered European network, data center, and colocation operator. It runs an extensive fiber backbone and data centers across Europe and Asia.
What it's used for
- Enterprise connectivity, IP transit, colocation, and data center services for large businesses and carriers.
Notable
- Primarily a network and data center operator rather than a mass-market VPS host, so addresses here tend to be enterprise or carrier infrastructure.
- Colt operates several ASNs across its regional footprint.

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.
