Russian Federation · AI-generated

government business russia

CTSPI is operated by FGUP CTSPI MGA Russia.

What it's used for

  • The address space is registered under the netname RU-CTSPI-20050201 with the registrant FGUP CTSPI MGA Russia.
  • The AS announces 4096 IPv4 addresses within a single prefix (80.73.16.0/20) and maintains 2 observed neighbours, indicating a small-scale internal or dedicated network rather than a large access or transit provider.

Notable

  • The registrant FGUP CTSPI MGA Russia matches the AS holder name, confirming consistent ownership of the announced space.
  • The inventory consists of a single contiguous /20 block, representing a compact and unified address estate.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-13, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Reputation

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.
