About this network

SAO-RAS is the Special Astrophysical Observatory of the Russian Academy of Sciences, a federal research institute in the North Caucasus that operates the BTA-6 optical telescope and the RATAN-600 radio telescope.

What it's used for

The AS announces 194.85.27.0/24 and 62.76.38.0/23 (~768 addresses) with a single observed neighbour. Sampled reverse DNS resolves under sao.ru (Core1.SAO.ru, cheetah.sao.ru), i.e. the observatory's own campus and scientific-computing hosts.

Notable

• This is a scientific research institution rather than a network operator; the tiny footprint and single upstream are typical of an academic site connected through a national research network.
• Reverse DNS names infrastructure and named hosts on sao.ru, consistent with institutional research use, not subscriber or commercial service.
