About this network

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.
