Summary

MTS

Russian Federation · AI-generated

mobile residential isp russia

TENSOR-AS is operated by MTS PJSC.

What it's used for

  • The address space carries residential and mobile access traffic, evidenced by reverse DNS entries like pppoe-94.136.215.254.ttel.ru and netnames such as MTU-ADSL.
  • With 37120 IPv4 addresses announced against only 1 observed neighbour, the ratio indicates a large access or eyeball network rather than a transit provider.

Notable

  • All registrants for the largest prefixes are consistent with the announcer, listing MTS backbone NOC and MTS PJSC.
  • The inventory consists of 10 IPv4 prefixes and 4 IPv6 prefixes, with the largest blocks being /19s in the 94.136, 95.175, and 109.198 ranges.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-13, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
