About this network

INESC is the Instituto de Engenharia de Sistemas e Computadores, a Portuguese research institute in systems and computer engineering, registered in Lisbon on Rua Alves Redol.

What it's used for

• Networking for research staff, laboratories and institute services across the INESC organisation.
• Its upstream is the Portuguese research and academic networking world rather than a commercial carrier, which is what places it firmly in the NREN-attached category.

Notable

• This is an institutional research network. The addresses are used by the institute itself, not sold to customers, so the space behaves like a campus rather than a provider.
• INESC has long been closely tied to Portuguese universities, and its network sits alongside them rather than in front of them.

Interesting

• INESC grew into a family of associated institutes across Portugal (Lisbon, Porto and others) that share a name and a research lineage while running largely independently. The registry entry keeps a single Lisbon anchor.
