Summary

MTS PJSC

Russian Federation · AI-generated

mobile isp ural russia

The AS handle TNGS-NORTH-AS is held by MTS PJSC.

What it's used for

  • The address space carries mobile and fixed access traffic, evidenced by netnames such as TNGS-NORTHNET, MTS-HMAO, and TNGS-SURGUT, and registrants including "Mobile TeleSystems PJSC Ural Branch" and "MTS backbone NOC".
  • The AS announces 22,528 IPv4 addresses across 17 prefixes with only 3 observed neighbours, a ratio that indicates an access or eyeball network rather than a transit provider.
  • Traffic from this AS consists of subscriber eyeballs for mobile and fixed-line customers in the Ural region of Russia, including dial-up and broadband users as suggested by the reverse DNS entry dialup-158.nptus.ru.

Notable

  • Registrants are consistent with the announcer, listing "Mobile TeleSystems PJSC Ural Branch", "MTS PJSC", and "MTS backbone NOC" across the largest prefixes.
  • The address inventory is composed of multiple /21, /22, and /24 blocks, reflecting a segmented corporate estate for regional operations.

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 1,781 prefixes, as published 2026-10-16. 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.
