Summary

Russian Federation · AI-generated

mobile residential isp russia

ALTAIRTULA-AS is operated by MTS PJSC.

What it's used for

  • The address space carries mobile and fixed-line subscriber traffic, evidenced by netnames such as RU-MTU-20091124 and RU-MTU-20030115 registered to MTS PJSC and MTS backbone NOC.
  • The AS announces 14,080 IPv4 addresses across 5 prefixes and 1 IPv6 prefix, while maintaining only 1 observed routing neighbour, a ratio characteristic of an access network rather than a transit provider.
  • Traffic from this AS consists of subscriber eyeballs for MTS's mobile and fixed-line services in the Russian Federation.

Notable

  • Registrants for the majority of prefixes are MTS PJSC, while the 89.107.192.0/23 prefix is registered to TK Altair Network, reflecting the historical origin of the AS handle ALTAIRTULA-AS before the consolidation under MTS.
  • The inventory includes a mix of /19, /20, /22, /23, and /24 IPv4 prefixes alongside a single /32 IPv6 prefix, indicating a legacy IPv4-heavy estate with limited IPv6 deployment.

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.
