Summary

MTS PJSC

Russian Federation · AI-generated

mobile residential isp russia

The AS handle TSVRN-AS is held by MTS PJSC.

What it's used for

  • The address space carries mobile and residential subscriber traffic, evidenced by netnames NET-TSVRN-CPE-5 and NET-TSVRN-CPE-6 and reverse DNS entries like ip212-45-228-0.rdns.tsvrn.ru.
  • With 9984 IPv4 addresses announced across 6 prefixes and only 1 observed neighbour, the network functions as an access provider rather than a transit hub.
  • Traffic consists of subscriber eyeballs and mobile data for MTS's customer base in the Russian Federation.

Notable

  • Registrants align with the announcer, listing MTS backbone NOC and MTS PJSC for the largest prefixes.
  • The inventory is concentrated in the 212.45.224.0/20 and 212.45.240.0/22 blocks, with a smaller allocation in 31.222.32.0/21.

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: 440 networks and 1,773 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.
