Summary

MTS PJSC

Russian Federation · AI-generated

mobile isp backbone russia

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

What it's used for

  • The address space carries MTS backbone and access traffic, evidenced by netnames RU-MTU and OOOSET-NET and reverse DNS entries pointing to zelenaya.net and stv.zelenaya.net.
  • The AS announces 34,560 IPv4 addresses across 27 prefixes and 1 IPv6 prefix, with 7 observed neighbours, indicating a large-scale access and backbone network rather than a pure transit provider.
  • Traffic from this AS consists of mobile subscriber eyeballs, fixed-line broadband users, and internal MTS infrastructure endpoints, consistent with MTS's role as a major Russian telecommunications operator.

Notable

  • Registrants align with the announcer, listing MTS backbone NOC, MTS PJSC, and LLC Set Main Operating Center for the majority of prefixes.
  • The address inventory is finely subdivided into numerous /21, /22, and /24 blocks, reflecting site-by-site segmentation typical of a large corporate and carrier estate.
  • The presence of LLC Set Main Operating Center registrants on some prefixes indicates historical or operational ties to the LLC SET entity, which operates under the MTS umbrella.

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: 446 networks and 1,852 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.
