Hosting RIPE
Summary
Duocast
hosting business netherlands
DUOCAST-AS is operated by Duocast B.V.
What it's used for
- The address space carries hosting and business infrastructure, evidenced by netnames such as
NL-CLOUD86-20190524(Cloud86 B.V.),NL-AKSI-20161205(AKSI Automatisering B.V.), andGRONNET(Provincie Groningen). - The AS announces 30720 IPv4 addresses across 36 prefixes and 25 IPv6 prefixes, while maintaining 141 observed neighbours. This high neighbour-to-address ratio indicates a transit or peering-heavy role rather than a large-scale residential access network.
Notable
- Registrants are mixed, including Duocast B.V., Youwe Concept B.V., Cloud86 B.V., AKSI Automatisering B.V., and Provincie Groningen, suggesting the AS aggregates space for multiple entities or has acquired their holdings.
- The inventory includes a diverse range of prefixes, from large /20 blocks to smaller /24s, with some space registered to third parties like Cloud86 and AKSI.
- Reverse DNS samples show infrastructure hostnames like
xe-0-0-1-107.er-r05.tcn.as31477.net, consistent with a hosting or data center environment.

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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
