Summary
AIST (Rostelecom, Samara/Tolyatti)
isp residential eyeball legacy
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.ruandIP-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.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 445 networks and 1,817 prefixes, as published 2026-10-27. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
