Germany · AI-generated

hosting cloud green germany

WINDCLOUD40-AS is operated by Windcloud 4.0 GmbH.

What it's used for

  • The address space carries cloud hosting infrastructure, with netnames such as Windcloud40-net and DE-WINDCLOUD1-20200529 directly identifying the operator's services.
  • The AS announces 2048 IPv4 addresses across 5 prefixes and 2 IPv6 prefixes, while maintaining 79 observed neighbours; this ratio of modest address space to high peering density indicates a transit or interconnection-heavy role rather than a large access network.
  • Traffic from this AS consists of web and API endpoints for sustainable cloud hosting services, as Windcloud 4.0 GmbH specializes in CO2-free cloud solutions powered by green electricity.

Notable

  • Registrants for most prefixes align with the announcer, listing Windcloud 4.0 GmbH, though the 128.0.64.0/23 block is registered to LeaderTelecom BV under the netname NL-LEADERTELECOMBV-20120914.
  • The address inventory includes a prefix (128.0.64.0/23) with a reverse DNS entry pointing to email.no-choice.de, which does not match the Windcloud branding and suggests a specific service or legacy allocation within the estate.

Reputation

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: 449 networks and 1,846 prefixes, as published 2026-11-03. 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.
