Summary

Unix-Solutions

Belgium · AI-generated

hosting datacenter cloud business

AS-UNIXSOLUTIONS is operated by Unix-Solutions BV.

What it's used for

  • The address space carries hosting and datacenter infrastructure, evidenced by netnames such as BE-UNIX-SOLUTIONS-20090826 and BE-CLOUDGROUP-20181221, and reverse DNS entries like vlan221-gw.zav.as39923.net.
  • The AS announces 17,920 IPv4 addresses across 27 prefixes and 7 IPv6 prefixes, while maintaining 99 observed neighbours; this ratio indicates a transit or peering-heavy role supporting its datacenter operations.
  • Traffic from this AS consists of cloud hosting, dedicated server, and datacenter services provided to business clients in Belgium.

Notable

  • Registrants for the majority of prefixes align with the announcer, including Unix-Solutions BV, NG Communications BV, Cloud Group NV, Lemon Companies BVBA, Econoweb BVBA, and Calrissia BV.
  • The address inventory is a mix of large /21 blocks and numerous smaller /22 and /24 prefixes, reflecting a diverse portfolio of acquired or allocated space.

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 1,775 prefixes, as published 2026-10-11. 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.
