Summary

Italy · AI-generated

business italy corporate

SFERANET-AS is operated by Register S.p.A., formerly known as Sfera Networks s.r.l.

What it's used for

  • The address space is associated with the registrant Register S.p.A., with netnames IT-SFERANET-20050608 and IT-SFERANET-20170328 indicating internal corporate infrastructure.
  • The AS announces 3584 IPv4 addresses across 3 prefixes and 2 IPv6 prefixes, maintaining only 2 observed neighbours, a ratio consistent with an internal corporate estate rather than a transit or access provider.

Notable

  • Registrants for all announced prefixes align with the AS holder, listing REGISTER S.P.A. and various Sfera.net administrative contacts.
  • The operator was formerly Sfera Networks s.r.l., as indicated by the AS handle description "Register S.p.A. ex Sfera Networks s.r.l."
  • The inventory consists of three IPv4 blocks (80.91.48.0/21, 185.196.160.0/22, 80.91.56.0/23) and two IPv6 prefixes, all located in Italy.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-16, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat

Hosting Datacenter or cloud provider. Addresses are servers, not people.

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 2026-10-17. 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.
