Unclassified RIPE NSP
Summary
NS3
isp residential italy
NS3-ASN is operated by NS3 s.r.l.
What it's used for
- The address space carries residential and business internet services, evidenced by reverse DNS entries such as
185-91-161-0.ns3.itand78-host64.ns3.it. - The AS announces 2048 IPv4 addresses across 4 prefixes and 2 IPv6 prefixes, with 33 observed routing neighbours. This ratio of address space to peering partners indicates an access network providing connectivity to end-users rather than a transit provider.
- Traffic from this AS consists of subscriber eyeballs, including residential broadband and small business connections, consistent with NS3's role as an Italian internet service provider.
Notable
- Registrants for the major prefixes align with the announcer, including
NS3 NOCandNS3 s.r.l.for the largest blocks, while78.26.127.0/24is registered toASDASD NOCand185.142.121.0/24toAbuse-C Role. - The inventory includes a mix of /22, /23, and /24 IPv4 prefixes, with the largest block being
185.91.160.0/22.

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 1,784 prefixes, as published 2026-10-19. 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.
