INTERNET ON DEMAND
IP Access Guide
INTERNET ON DEMAND OVERVIEW
Internet On Demand is an enterprise grade Dedicated Internet Access (DIA) service, with support for both wires only and managed router variants.
The service is based on Colt's own ASN (8220). We do not currently resell Internet services from 3rd party providers via our On Demand platform.
The service is available in all core Colt countries where , delivered over Colt fibre (on-net) or 3rd party Ethernet tails (off-net).
WIRES ONLY ("ROUTERLESS") INTERNET ACCESS
Internet On Demand services are supported on standard On Demand ports in data centres and enterprise locations. Internet connectivity is available at on-net and off-net buildings in the following locations in Europe, Asia Pacific and North America. Bandwidths up to 10Gbps are now supported across all locations for Wires Only connections.
On-net locations (connected with Colt Fibre)

Austria, Belgium, Bulgaria, Czechia, Denmark, France, Germany, Hungary, Ireland, Italy, Luxembourg, Netherlands, Poland, Portugal, Romania, Serbia, Slovakia, Spain, Sweden, Switzerland, United Kingdom
On-net locations (connected with Colt Fibre)

Customers benefit from the same carrier class internet experience as the standard Colt IP Access service (which is based on market-leading internet peering) with the added benefit of On Demand capabilities such as flexible contract options and temporary bandwidth scaling via the Bandwidth Boost feature.
The “wires-only” option means that customers are required to provide a router at the data centre or enterprise building where the On Demand port terminating the Internet OD connection is located. Connecting the Internet OD service directly to the customer’s LAN without is not currently supported and will result in a misconfiguration.
The location of the port determines the location of Colt’s core IP router that is used to parent the Internet On Demand service. For example, an Internet On Demand service terminating on an On Demand port in Frankfurt will be parented from Colt’s core IP router based in Frankfurt.
Under the On Demand model, Internet services are treated as circuit connections that can be terminated on a standard port in a data centre or enterprise building. The Internet connection port can be presented on a dedicated port (i.e. one Internet OD connection per port) or on a multi-service port where other Ethernet, Cloud or Internet connections are terminated.
The provisioning journey for Internet OD is straightforward; customers simply have to choose:
All other configuration parameters (for example, IP address ranges) are automatically applied by the On Demand platform.
Once an Internet On Demand connection is live, customers are able to upgrade the bandwidth permanently (via a fixed contract), upgrade or downgrade the bandwidth temporarily (via a flex contract) and change the VLAN parameters or contractual commitment.
MANAGED INTERNET ACCESS (VIA A VIRTUAL ON DEMAND ROUTER)
Managed Internet On Demand services based on a virtual instance (vRouter) are now supported via Colt On Demand.
The managed Internet service is available in all on-net and off-net locations in the UK and France, with support for additional countries planned for later in 2025/26.
The vRouter service is available in bandwidths from 10Mbps to 1Gbps.
IP ADDRESSES
Colt provides a /30 range for the WAN connection, the first usable IP address being the IP address allocated to the port on the Colt core IP router.
When an Internet On Demand connection is activated, Colt will allocate a block of /29 Provider Aggregated (PA) addresses based on IPV4 which can be used on the LAN side of the customer equipment (e.g. router, firewall, Access Point).
8 LAN addresses are available by default, with no extra charge. Additional IP addresses are available at an extra cost, in blocks of 16, 32 or 64 addresses — i.e. blocks of /28, /27, /26 respectively.

The addresses for the primary/secondary DNS servers used by Colt are shown below:
Primary DNS server
195.110.64.205
Secondary DNS server
212.121.128.10
IP BACKBONE NETWORK
Colt has made a substantial investment in the creation of a dedicated IP-based network to provide flexible, scalable IP-based solutions to the mission-critical Internet needs of our customers.
Colt is also a key participant in major European and Asian direct and indirect peering and partnership agreements, enhancing its capability to provide customers with the highest levels of service worldwide.
Internet On Demand services are based on the same network platform as traditional IP Access services.
