About this network

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-20050510 and IT-AMPERSAND-20130325 and reverse DNS entries like netaround80h255.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, 80.86.48.0/20 and 185.22.36.0/22, alongside a single IPv6 prefix 2a02:29a0::/32.
