AS-ORANJEKOEK is held by Arend Brouwer.

What it's used for

  • The address space carries mixed registrations, including ARCADIS-PL for Arcadis Spolka z ograniczona odpowiedzialnoscia and NL-ERITAP-20130801 for ERITAP NOC.
  • The AS announces 512 IPv4 addresses and 28 IPv6 prefixes while maintaining 45 observed neighbours, a ratio that indicates a transit or peering role rather than an access network.
  • Traffic from this AS consists of routed IP space for the registered entities, with the ERITAP netname suggesting association with the network services provider identified in PeeringDB.

Notable

  • Registrants differ from the AS holder, with Arcadis Spolka z ograniczona odpowiedzialnoscia and ERITAP NOC listed for the announced IPv4 prefixes.
  • The address inventory is small, comprising two IPv4 prefixes and a set of IPv6 prefixes under the 2a10:e300::/43 block.

Classification and threat

Hosting Datacenter or cloud provider. Addresses are servers, not people.

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 1,778 prefixes, as published 2026-10-20. 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.
