The Network

Home > The Network

HEAnet  connects over one million users to the Internet, linking them to each other and the rest of the world via our secure, high-capacity national education network.

The HEAnet  Network is made up of our “national backbone” using ESBT Fibre and the Dublin Core Ring – this is the basis for all HEAnet Connectivity Services.

Dark Fibre between the major cities and urban areas allows us to deliver national coverage, providing the same high quality Internet access to all our clients, regardless of their location on the island of Ireland.

The national backbone consists of over 2,500Km of fibre and interconnects all Higher Education Institutions in Ireland, as well as providing backhaul for over 4,000 primary & post-primary schools across the country.
