Summary

SD WORX People Solutions

Belgium · AI-generated

business belgium corporate

What it's used for

  • The address space is registered under the netname ORG-SWPS2-RIPE for SD WORX People Solutions, indicating a corporate allocation.
  • The AS announces 768 IPv4 addresses across 3 prefixes with only 1 observed neighbour, a ratio consistent with an internal corporate estate or site-specific connectivity rather than a transit or access provider.

Notable

  • All three announced prefixes (91.216.238.0/24, 193.109.234.0/24, 195.85.246.0/24) share the same registrant and netname, confirming a unified ownership structure.

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 1,779 prefixes, as published 2026-10-21. 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.
