isp residential regional cable

The AS handle EMISFERA-AS is held by Emisfera Societa' Cooperativa.

What it's used for

  • The address space carries residential and business internet access, evidenced by reverse DNS entries such as host-45-81-66-254.emisfera.it and netnames like IT-EMISFERA-20160329 and EMISFERA-NET.
  • The network announces 2304 IPv4 addresses across 3 prefixes and 1 IPv6 prefix, while maintaining 30 observed neighbours; this ratio of address space to peering partners indicates a regional access provider rather than a transit hub.
  • Traffic from this AS consists of subscriber eyeballs for cable and DSL users in the Verbania region, as Emisfera operates as a regional ISP providing connectivity services.

Notable

  • Registrants for the two largest prefixes are Emisfera Societa' Cooperativa, while the 45.81.64.0/22 block is registered to Viatek Srl under the netname IT-VIATEK-20190517.
  • The address inventory is composed of three distinct IPv4 blocks, with the 45.81.64.0/22 and 185.144.212.0/22 blocks being the largest allocations.

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: 448 networks and 1,849 prefixes, as published 2026-10-29. 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.
