shipping gas corporate belgium

EXMAR is operated by Exmar nv.

What it's used for

  • The address space carries corporate infrastructure for a shipping and gas transportation company, as indicated by the netname BE-EXMAR-20180423 and registrant Exmar nv.
  • The AS announces 1024 IPv4 addresses within a single prefix (128.0.156.0/22) and maintains 2 observed neighbours, a ratio consistent with a small internal corporate estate rather than a transit or access network.
  • Traffic from this AS consists of office workers, web/API endpoints, and internal systems supporting Exmar's operations in the transportation of liquefied gas products and ship management.

Notable

  • The RDAP registrant Exmar nv agrees with the AS handle EXMAR and the registry holder.
  • Exmar is a publicly listed company on the Belgian Euronext, specializing in floating solutions for the operation, transportation, and transformation of gas.

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 2026-10-29. 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.
