hosting cloud transit bulgaria

BELCLOUD is operated by Belcloud LTD, a Bulgarian cloud hosting provider based in Sofia.

What it's used for

  • The address space carries cloud hosting and infrastructure services, with netnames including BG-BELCLOUD-20190806 and CY-REDCLUSTER-20170512.
  • The AS announces 19,712 IPv4 addresses across 49 prefixes and 2 IPv6 prefixes, while maintaining 1,804 observed neighbours, indicating a role focused on transit and interconnection rather than residential access.
  • Traffic from this AS consists of web hosting, S3-compatible object storage, and scalable compute endpoints for enterprise and developer clients.

Notable

  • Registrants align with the announcer for Belcloud-owned blocks, while several prefixes are registered to Redcluster LTD and S3 Company Ltd, suggesting historical acquisitions or managed infrastructure relationships.
  • The inventory includes a mix of /22 and /23 blocks, with some prefixes registered under the CY-REDCLUSTER netname, reflecting a consolidated estate from multiple sources.

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: 431 networks and 1,768 prefixes, as published 2026-10-12. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

3 IC3 indicators addresses in this network appear in FBI IC3 cybersecurity advisories.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
