business dredging corporate

DMM is the autonomous system for Jan De Nul Dredging NV.

What it's used for

  • The space carries corporate network traffic, indicated by the netname JDN-LUX-EXTERNAL associated with the announced prefix.
  • The AS announces 256 IPv4 addresses across 1 prefix with 2 observed neighbours, a ratio consistent with a small internal corporate estate rather than a transit or access provider.
  • Traffic from this AS consists of office workers and operational endpoints for a global dredging and offshore energy company.

Notable

  • The registrant Abuse-C Role for the prefix 193.148.10.0/24 aligns with the registry holder DMM Jan De Nul Dredging NV.
  • Jan De Nul is a family-owned Belgian company with a financial headquarters in Luxembourg, operating in offshore energy, dredging solutions, construction projects, and planet redevelopment.
  • The address inventory is a single /24 block, representing a compact and self-contained corporate network footprint.

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 1,852 prefixes, as published 2026-10-27. 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.
