The right support

GN-IX offers a range of services:

  • Peering
  • Marketplace
  • Connectivity (Layer 2 or WDM)
  • Hands on services


ISP's, which include Access, Content, Hosting, Mobile and Application Service Providers, use the GN-IX infrastructure primary for exchanging IP traffic on a settlement-free basis, called `peering'. In this way, ISP's can reduce their Internet connectivity costs. Through the GN-iX route-servers, it’s possible to exchange traffic with peering-members of the AMS-IX, FR-IX,   ND-IX and R-iX.


Marketplace ports can be used to exchange various services on a secure way with other marketplace customers. With one marketplace port you can connect to multiple customers (with multiple VLANS). Services provided are I.E. internet connectivity, VoIP and backup services. With our EU-Open partnership it is also possible to connect to providers who are connected to marketplace ports on the or EFX, FR-IX, ND-IX or R-iX.


GN-IX offers connectivity between multiple datacenters in the Northern Netherlands. You can use this service to connect equipment between multiple locations for I.E backup purposes or a twin datacenter concept.

GN-IX offers two types of connectivity:


VLANS or layer 2 networks, can be used between two or more datacenters. It’s possible to use your own VLAN numbers on this connection (Q-in-Q tunnel).

2. WDM

WDM or private waves are always point-to-point. WDM offers guaranteed bandwidths and a low latency.  Please contact us to inform to the opportunities.

Hands on services

In close cooperation with Center of Information Technology (CIT) and Bytesnet GN-IX offers the possibility to support customers with high quality services by highly educated technical engineers.

Connecting the dots

The GN-IX network infrastructure operates on a number of high performance layer two switches from Cisco Systems. The switches are placed in multiple datacenters in Groningen. A private dark fiber ring running Gigabit ethernet connects these sites.

GN-IX also has various routers providing IPv4 and IPv6 connectivity for GN-IX's own systems and management of the switched network. For peering, GN-IX provides redundant route-servers to simplify the management of peering sessions. Through the route-servers, it’s possible to peer with providers on the EU-OPEN partnership exchanges and the AMS-IX.

The GN-IX network provides the following media for customer connections:

  • 100 BaseTX Ethernet - All switches provide 100/1000 Mbps switched Ethernet ports.
  • 10 Gigabit Ethernet - The primary sites can also provide a non-blocking 10 Gigabit Ethernet service to members. 


GN-IX has a high quality infrastructure and offers its customers the following facilities:

  • 4 Cisco 6500 switches (1000Base-TX / 1000Base-(SX/LX/T) / 10Gbase-ports)
