About this network

TENET-AS belongs to TENET Scientific Production Enterprise LLC, a fixed-line broadband provider serving the city of Odesa, Ukraine.

What it's used for

• Residential and small-business internet access across Odesa, delivered over TENET's own city-wide fibre ring, alongside digital TV, telephony, and some hosting and data-centre services.
• Reverse DNS is unambiguous about the subscriber role: pools resolve as …broadband.tenet.odessa.ua and Od-Port-…tenet.odessa.ua, the classic shape of an eyeball access network.

Notable

• This is a genuine eyeball ISP rather than a carrier backbone. Around 112k IPv4 addresses sit behind it, spread across dozens of prefixes plus an IPv6 /29, which is a sensible footprint for a metro broadband operator.
• TENET is a city-scale operator, not a national one. Its network and its registered address are both in Odesa.

Interesting

• The "Scientific Production Enterprise" in the legal name is a holdover from a post-Soviet corporate form and does not indicate a research network. The operator's business is consumer and business connectivity.
