Summary

Oceanco

Netherlands · AI-generated

business maritime corporate

OCEANCO is the autonomous system for Oceanco Alblasserdam Yachtbuilding B.V.

What it's used for

  • The space carries corporate IT infrastructure, identified by the netname NL-OCEANCO-20140312 and registrant Oceanco IT Department.
  • The AS announces 1024 IPv4 addresses across 1 prefix (185.50.60.0/22) with 2 observed neighbours, indicating a small, self-contained corporate network rather than a transit or access provider.
  • Traffic from this AS consists of internal corporate communications, office workers, and web/API endpoints for a luxury yacht manufacturer.

Notable

  • The registrant Alblasserdam Yachtbuilding B.V.; Oceanco IT Department aligns directly with the AS holder and the OCEANCO handle.
  • The address inventory consists of a single contiguous /22 block, typical for a single-site corporate estate.

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.
