Summary

SDNum SAS

France · AI-generated

business france ipv4

The AS handle SDNUM-SAS is held by SDNum SAS.

What it's used for

  • The address space carries business and enterprise traffic, evidenced by netnames FR-HEXANET1-20110310 and FR-WIZEO-SAS associated with registrants HEXANET SAS and Wizeo SAS.
  • The network announces 8192 IPv4 addresses across 5 prefixes with only 1 observed neighbour, indicating a small-scale internal or corporate estate rather than a transit or large access network.
  • Traffic from this AS consists of office workers and internal corporate endpoints, consistent with the business nature of the registrants.

Notable

  • Registrants include HEXANET SAS and Wizeo SAS, which differ from the AS holder SDNum SAS, suggesting leased space or post-acquisition history.
  • The address inventory is finely subdivided into five prefixes within the 31.29.96.0/20 range, reflecting site-by-site segmentation typical of an internal corporate estate.

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: 447 networks and 1,843 prefixes, as published 2026-11-02. 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.
