About this network
ACOnet (ACONET) is Austria's national research and education network, serving science, research, education, art, and culture. It is operated by the Computer Center of the University of Vienna.
What it's used for
- A nationwide fibre backbone connecting Austrian universities and research institutions, with high-performance links to the pan-European GÉANT network.
Notable
- A national research and education network (NREN), not a commercial ISP.
Interesting
- Operated by the University of Vienna since 1992, which also runs the Vienna Internet Exchange; a genuinely early allocation rather than a reissued low number.
