Summary
Terna
utility infrastructure italy
The AS handle GRTN-AS is held by Terna S.p.A., the Italian electricity transmission system operator.
What it's used for
- The address space carries infrastructure for Terna's grid operations, evidenced by the netname
GRTN-NETand registrantTerna S.p.A. - The inventory consists of a single IPv4 prefix, 193.108.204.0/24, comprising 256 addresses, with 1 observed neighbour, indicating a small, isolated internal network rather than a transit or access provider.
Notable
- The registrant
Terna S.p.A.aligns directly with the AS holder, confirming the space is owned and operated by the utility itself. - The address inventory is minimal, consisting of only one /24 block, which is typical for a corporate entity managing specific internal systems rather than a large-scale internet service provider.

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 1,772 prefixes, as published 2026-10-15. 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.
