About this network

EENet-AS is EENet, Estonia's national education and research network. The ASN is registered to Haridus- ja Teadusministeerium — the Estonian Ministry of Education and Research — in Tartu.

What it's used for

• The national research and education backbone: connectivity for Estonian universities, research institutes, schools, libraries, and public education bodies.
• Shared services for the academic sector and the Estonian link into the wider European research networking community.

Notable

• An NREN address footprint: roughly 65,000 IPv4 addresses serving institutions and campus users, not paying broadband subscribers.
• The ASN sits directly under the education ministry, reflecting EENet's absorption into the state education administration rather than a standalone operator.

Interesting

• Estonia connected its academic network early and has kept the same low AS number through repeated reorganisations of who formally operates EENet.
