Russian Federation · AI-generated

transit isp russia

MSTN-AS is operated by MSTN CJSC.

What it's used for

  • The address space is registered under netnames RU-MSTN-20110810, RU-MSTN-20080623, and RU-MSTN-20151202, with registrants listed as MSTN CJSC; MSTN ABUSE.
  • The AS announces 5888 IPv4 addresses across 5 prefixes and 1 IPv6 prefix, while maintaining 28 observed neighbours, a ratio indicative of a transit or network service provider role.
  • As a regional network service provider, the traffic consists of upstream transit and interconnection for downstream customers and enterprise clients.

Notable

  • Registrants for the majority of prefixes align with the announcer, identifying MSTN CJSC as the holder.
  • The prefix 5.188.52.0/22 is registered to PINDC Support and NOC Teams under the netname RU-RIaaS, distinguishing it from the other MSTN-owned blocks.
  • The inventory includes a mix of /21, /22, /23, and /24 IPv4 blocks alongside a single /32 IPv6 prefix.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-10, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
