Summary

Compania Nationala Aeroporturi Bucuresti SA

Romania · AI-generated

airport corporate infrastructure business

CNAB-AS is the autonomous system for Compania Nationala Aeroporturi Bucuresti SA, the state-owned operator of Bucharest's international airports.

What it's used for

  • The address space is registered to Serviciul de Telecomunicatii Speciale (STS) under the netname RO-STS1-20120914, indicating the infrastructure is provisioned by Romania's special telecommunications service.
  • The AS announces 512 IPv4 addresses in a single prefix (176.126.220.0/23) with 2 observed neighbours, a ratio consistent with a small, dedicated corporate or facility network rather than a transit or large-scale access provider.
  • Traffic from this AS supports the operational and administrative functions of Bucharest's airport infrastructure, including internal systems and facility management for the Henri Coandă and Băneasa airports.

Notable

  • The registrant Serviciul de Telecomunicatii Speciale differs from the AS holder, reflecting the use of a specialized state telecom provider for the airport's network infrastructure.
  • The inventory consists of a single contiguous /23 block, indicating a compact and self-contained address allocation for the airport's internal use.

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: 453 networks and 1,846 prefixes, as published 2026-11-11. 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.
