Summary

VEM Sistemi

Italy · AI-generated

business italy corporate

The AS handle VEM-SISTEMI is held by VEM Sistemi S.p.A.

What it's used for

  • The space carries corporate infrastructure, evidenced by the reverse DNS record host-254-234-234-195.vem.com and the netname VEM-SISTEMI.
  • The AS announces 1024 IPv4 addresses within a single prefix (195.234.232.0/22) and maintains 2 observed neighbours, indicating a small, self-contained corporate network rather than a transit or large-scale access provider.

Notable

  • The RDAP registrant VEM SISTEMI S.p.A. matches the AS holder, confirming consistent ownership of the address space.
  • The address inventory consists of a single /22 block, representing a compact and unified corporate estate without significant subdivision or external leasing.

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 1,778 prefixes, as published 2026-10-20. 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.
