Cork Neutral Internet eXchange Association Limited

Cork Neutral Internet Exchange Association Limited (CNIX) is a not-for-profit association. It was founded on June 30th, 2009, by leading members of the Cork business community. Its fundamental aim is to support the local economy by building local infrastructure to enable higher capacity, lower latency and lower cost data transfer to homes and businesses in the Munster region.

Active Projects

  • Cork IX: provides a high-speed, reliable and resilient Internet traffic exchange facility in Cork, thereby providing faster, more reliable and lower-latency internet access.
  • National IX: CNIX is, in turn, a peer to the national Internet Neutral eXchange (INEX) and as a result offers its members cost effective aggregation of peering to the national Internet eXchange.
  • Distributed Denial of Service Mitigation: is facilitated by CNIX on behalf of Members by providing infrastructure to implement RFC 3882.
  • OpenBL: is a global collaborative project to detect, log and report IP addresses that originate a number of types of Internet abuse. CNIX maintains a route server which is updated daily with detected attacking IP addresses. Members can use this service to black all traffic to these suspect IP addresses
  • Cloud Valley: is a high speed (160Gbps) wave division multiplexed (WDM) fiber ring around Cork City to increase network capacity to that required for emerging applications such as cloud computing, big data and video on demand applications.
To date, all of the equipment, hosting and solution development effort required by CNIX has been contributed by members without charge.


Application for Associate Membership of CNIX is open to any organisation (including a person or sole trader) that wishes to observe or assist the activities of the Association. An application must be proposed by an existing member and accepted by a minimum of 60% of the current members. More than one person from a member organisation can attend meetings. All member organisations have a single vote to elect officers and to change rules. However it is expected that individual projects are managed by active participants. An active participant is defined as a member contributing effort or resources and sharing the cost of a project.
