Summary
Telecom Italia
telecom business enterprise italy
The AS handle ASN-IDC T.NO.OM.I.NC is held by Telecom Italia S.p.A., the leading Italian telecommunications provider.
What it's used for
- The address space carries business and enterprise services, evidenced by netnames such as
IT-INTERBUSINESS-20020708andIT-FULLCOMPANY-20001017, and reverse DNS entries likehost-81-126-200-0.business.telecomitalia.it. - With 215,296 IPv4 addresses announced across 229 prefixes and only 12 observed neighbours, the high address-to-neighbour ratio indicates an access or eyeball network rather than a transit provider.
Notable
- Registrants for the largest prefixes consistently identify
Telecom Italia S.p.A.or its business units, such asInterbusiness Network Administration StaffandIT Telecom Role, aligning with the announcer. - The address inventory is finely subdivided into numerous /21 and /20 blocks, reflecting a large internal corporate estate segmented by service type or site rather than a single monolithic allocation.

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-19, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,783 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.
