Summary

MTS PJSC

Russian Federation · AI-generated

mobile residential access russia

MR-SIB-MTSAS is operated by MTS PJSC, the major Russian mobile and fixed-line telecommunications provider.

What it's used for

  • The address space carries consumer and mobile access traffic, evidenced by reverse DNS entries such as ppp85-140-100-0.pppoe.mtu-net.ru and host-212-109-201-0.sib.mts.ru.
  • With 8192 IPv4 addresses and 20 IPv6 prefixes announced against only 7 observed neighbours, the ratio indicates an access or eyeball network rather than a transit provider.

Notable

  • Registrants are consistent with the announcer, primarily listing MTS backbone NOC and MTS PJSC, with some blocks registered to MR-SIB-MTS Administration.
  • The inventory is finely subdivided into 8 IPv4 prefixes, including a large /20 block (85.140.96.0/20) and several /23 blocks, reflecting site-by-site segmentation within the corporate estate.
  • One prefix (185.52.140.0/23) lists Overta Internet Center as a registrant alongside MTS entities, suggesting historical or specific operational associations.

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: 442 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.
