Summary

Aeroflot

Russian Federation · AI-generated

airline corporate business russia

AEROFLOT is the autonomous system for PJSC Aeroflot, the largest airline in Russia.

What it's used for

  • The address space carries corporate infrastructure for the airline, evidenced by reverse DNS entries pointing to aeroflot.ru and netnames like RU-AEROFLOT-20010919 and RU-AEROFLOT-SVO2.
  • The AS announces 1280 IPv4 addresses across 3 prefixes with 3 observed neighbours, a ratio consistent with an internal corporate estate rather than a transit or access network.

Notable

  • Registrants align with the announcer, with PJSC Aeroflot listed for the primary block and Abuse-C Role for others, confirming a single organizational owner.
  • The inventory consists of three contiguous IPv4 prefixes within the 80.92.32.0/22 range, indicating a finely subdivided internal network.
  • No IPv6 prefixes are currently announced in the inventory.

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: 447 networks and 1,843 prefixes, as published 2026-11-01. 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.
