Summary
Ampersand Srl
isp cable dsl regional
AMPERSAND-AS is operated by Ampersand Srl, a regional internet service provider based in La Spezia, Italy.
What it's used for
- The address space carries residential and business internet access, as indicated by the registrant netnames
IT-AMPERSAND-20050510andIT-AMPERSAND-20130325and reverse DNS entries likenetaround80h255.cdh.it. - The AS announces 5,120 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, while maintaining 22 observed neighbours; this ratio of modest address space to a significant number of peering partners is characteristic of a regional access network rather than a large transit provider.
- Traffic from this AS consists of subscriber eyeballs for cable and DSL connections in the Liguria region of Italy.
Notable
- The registrants for both announced IPv4 prefixes are listed as
Ampersand Srl; Ampersand NOC, which aligns directly with the AS holder. - The address inventory is composed of two distinct IPv4 blocks,
80.86.48.0/20and185.22.36.0/22, alongside a single IPv6 prefix2a02:29a0::/32.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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 1,773 prefixes, as published 2026-10-13. 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.
