IP Connectivity Hero Image

What Sets Us Apart offers a superior, Pan-European 100G/400G network with exceptional connectivity to carriers, content providers, and internet exchanges.

We operate two ASNs that we are bringing together so you can access powerful IP and flexible private L2 connectivity on-demand. 

  • ASN 25291 (INTERDOTLINK-SYSELEVEN) is our historical ASN with over 1400 peers and strong reach to European content audiences with minimal latency, outperforming many larger Tier 1 and Tier 2 providers.
  • ASN 5405 (INTERDOTLINK) is our new ASN that is deeply integrated with Flex Ethernet and Network Function services. We are actively planning migration of all connectivity and customers to this ASN. 

Experience the benefits of our network for yourself by signing up for a free trial.

Peering Partners


BGP FlowSpec

DDoS attacks can cripple a network and can take up extensive time and resources. So, it makes sense to be proactive and not just reactive. With our IP-Transit, you can use FlowSpec, or a separate BDP session. Additionally, customers can announce FlowSpec filter rules that will be installed on our network. 

This approach makes it easier to help mitigate a DDoS attack before it reaches the customer's network. 

Bring Your Own ASN (BYOA)

Managing internet infrastructure is no easy task. If you find yourself in a situation where you have an AS number and IP address space, then we can help. 

Our services allow you to use your own IP address space under your ASN in combination with our IP-Access product. 

Additionally, we can provide assistance in setting up an RIR (RIPE) LIR membership. So, let us help you get on the right track. 

DDoS Filtering Mitigation

Using our automated portal, customers can announce filter rules (similar to FlowSpec) that they would like to have installed on our network. This allows easy customer-controlled filtering to mitigate a DDoS attack before it reaches the customer's network.
