Summary

3 D.A. di Domeneghini Angelo

Italy · AI-generated

business italy small

IT-3DA is operated by 3 D.A. di Domeneghini Angelo, a sole proprietorship based in Concesio, Italy.

What it's used for

  • The address space is registered under the netname NET-3DA for the individual business entity.
  • The AS announces a single IPv4 prefix, 195.54.60.0/23, comprising 512 addresses, with no IPv6 inventory.
  • With only one observed neighbour, the network functions as a small, isolated site or internal corporate estate rather than a transit or access provider.

Notable

  • The registrant 3 D.A. DI DOMENEGHINI ANGELO - Impresa Individuale matches the AS holder, confirming direct ownership of the address space.
  • The inventory consists of a single contiguous /23 block, indicating a simple, non-subdivided 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: 447 networks and 1,849 prefixes, as published 2026-10-30. 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.
