Summary

Computer Design Srl

Italy · AI-generated

business italy corporate

The AS handle COMPUTERDESIGN-AS is held by Computer Design Srl.

What it's used for

  • The address space carries corporate infrastructure, evidenced by the reverse DNS entry ws.eurapp-demo.cdesign.it and netnames such as IT-CDESIGN-20010329 and CDIT-WWW.
  • The network announces 1792 IPv4 addresses across 6 prefixes with only 1 observed neighbour, a ratio that indicates an internal corporate estate rather than a transit or access provider.

Notable

  • Registrants for the largest prefixes are consistently Computer Design Srl or Abuse-C Role, aligning with the AS holder.
  • The inventory consists of six contiguous /24 blocks and one /23 block within the 217.170.224.0/21 range, all located in Italy.

Reputation

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: 448 networks and 1,851 prefixes, as published 2026-11-03. 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.
