Summary

Mediacaster

Netherlands · AI-generated

business datacenter netherlands

The AS handle MEDIACASTER-AS is held by Mediacaster B.V.

What it's used for

  • The address space carries corporate infrastructure and datacenter services, evidenced by netnames NL-CLOUDBRAINS-20170126 and MEDIACASTER-CORPCUST-NET, and reverse DNS entries such as net-185.187.125.cloudbrains.nl and controller1.mediacaster.nl.
  • The AS announces 2304 IPv4 addresses and 3 IPv6 prefixes across 5 IPv4 prefixes, with only 3 observed neighbours, indicating a business or datacenter network rather than a transit provider.
  • Traffic consists of datacenter endpoints, cloud services, and corporate network management systems for Mediacaster and its subsidiary CloudBrains.

Notable

  • Registrants include MediaCaster Datacenter en Netwerken B.V., MEDIACASTER NOC, Stichting Cosis, and Wirewizard Management BV, with the largest block registered to the datacenter subsidiary.
  • The address inventory includes a /22 block for CloudBrains and several /24 blocks for corporate and customer use, with one /24 registered to Stichting Cosis.

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 1,783 prefixes, as published 2026-10-17. 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.
