About this network

GRNET is Greece's National Research and Education Network, the backbone connecting the country's universities, research centres, and public bodies to each other and internationally.

What it's used for

• Linking Greek universities, research institutes, and schools over a national high-speed backbone, with onward peering to GÉANT and the wider internet.

Notable

• As an NREN, addresses here belong to connected academic and research institutions, classified education rather than commercial hosting.
• GRNET also operates national cloud, HPC, and e-infrastructure services for the Greek research and education community.
