Summary

Port of Constanta

Romania · AI-generated

port business maritime infrastructure

TRIDENT-AS is operated by Compania Nationala Administratia Porturilor Maritime SA Constanta.

What it's used for

  • The address space carries internal port operations, evidenced by netnames ORG-CNAP1-RIPE and APC-NET registered to the port authority and its NOC.
  • The AS announces 768 IPv4 addresses across 2 prefixes with only 2 observed neighbours, indicating a small, self-contained corporate network rather than a transit or access provider.
  • Traffic consists of internal administrative, logistics, and operational systems for the Port of Constanta, Romania's largest seaport.

Notable

  • Registrants align with the announcer, listing Compania Nationala Administratia Porturilor Maritime SA Constanta and COMPANIA NATIONALA "ADMINISTRATIA PORTURILOR MARITIME" - S.A. CONSTANTA; APC NOC.
  • The inventory is compact, consisting of one /23 and one /24 block, typical for a single-site corporate estate.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-15, 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: 442 networks and 1,782 prefixes, as published 2026-10-16. 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.
