Engineering D.HUB S.p.A.
business enterprise italy engineering
The AS handle ASN-DEBIS is held by Engineering D.HUB S.p.A., an Italian enterprise.
What it's used for
- The address space carries corporate infrastructure, evidenced by netnames such as
IT-DEBISandIT-ENGINEERING-20120614, and reverse DNS entries pointing tonet.psmidc.com. - With 84,992 IPv4 addresses announced across 18 prefixes and 32 observed neighbours, the inventory suggests a large internal corporate estate rather than a transit or access network.
Notable
- Registrants consistently identify as
Engineering D.HUB S.p.A.orENGINEERING INGEGNERIA INFORMATICA SPA, aligning with the announcer. - The address inventory is finely subdivided into multiple /22 and /24 blocks, indicating site-by-site segmentation typical of a large corporate network.
- The presence of the
PSMIDCnetname on the largest block (161.27.0.0/16) suggests a specific data center or managed service component within the broader Engineering group.

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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
