About this network

AIST (AIST) — a broadband provider in the Samara region of Russia, now held by PJSC Rostelecom after the incumbent absorbed it. It served the Samara and Tolyatti conurbation under the AIST and "100 Megabit" brands.

What it's used for

• Consumer broadband access. Sampled addresses resolve as IP-ADDR.clients.tlt.100megabit.ru and IP-ADDR.clients.smr.100megabit.ru — subscriber pools keyed to Tolyatti (tlt) and Samara (smr).
• A handful of operational hosts remain on the original domain (vpn1.smr.aist.net.ru, ns1.tlt.aist.net.ru).

Notable

• An eyeball network: the space is home internet, not hosting.
• The registered holder is Rostelecom, but the rDNS still carries the acquired brand. Geolocation should follow the city hints in the rDNS rather than Rostelecom's national footprint.

Interesting

• Rostelecom grew largely by buying regional ISPs like this one, and the acquired networks often keep announcing under their own AS numbers and their own reverse-DNS domains for years afterwards.
