Summary

Tallinn Airport

Estonia · AI-generated

airport infrastructure estonia

TLL-AERO-AS is held by AS Tallinna Lennujaam.

What it's used for

  • The space carries airport infrastructure, evidenced by reverse DNS entries a128.tll.aero and b126.tll.aero and the netname TLL-AERO.
  • The AS announces 512 IPv4 addresses within a single prefix (195.8.204.0/23) and maintains 2 observed neighbours, indicating a small, self-contained internal network rather than a transit or access provider.
  • Traffic from this AS consists of internal airport systems, operational endpoints, and facility management infrastructure for Tallinn Airport.

Notable

  • The RDAP registrant lists both Citic Telecom CPC Network Operations and AS Tallinna Lennujaam for the prefix 195.8.204.0/23, suggesting a relationship between the airport operator and the telecom entity managing the address space.
  • The address inventory is compact, consisting of a single /23 block, which aligns with the limited scope of a single-site corporate or facility network.

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: 448 networks and 1,849 prefixes, as published 2026-10-30. 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.
