Summary

Ubicentrex

France · AI-generated

business france ipv4

ASUBI is operated by Ubicentrex SAS.

What it's used for

  • The address space carries business traffic, evidenced by the netname FR-UBICENTREX-20180131 and reverse DNS entries pointing to not-updated.ubicentrex.net.
  • The AS announces 1024 IPv4 addresses across 1 prefix (185.132.232.0/22) and maintains 3 observed neighbours, a ratio consistent with a small-scale business or enterprise network rather than a transit provider.
  • Traffic from this AS consists of corporate or enterprise endpoints associated with Ubicentrex, a French telecommunications and IT services provider.

Notable

  • The RDAP registrant UBICENTREX SAS aligns with the AS holder ASUBI UBICENTREX SAS, confirming consistent ownership.
  • The inventory consists of a single contiguous /22 block, indicating a compact and unified address allocation.

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: 453 networks and 1,846 prefixes, as published 2026-11-12. 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.
