isp residential italy cable

NEMO-AS is operated by Nemo S.r.l., an Italian cable and DSL internet service provider.

What it's used for

  • The address space carries residential and business internet access, evidenced by the PeeringDB classification as a Cable/DSL/ISP and the netname IT-NEMO-20131009 associated with the operator's own prefix.
  • The AS announces 2,304 IPv4 addresses across 3 prefixes while maintaining 30 observed routing neighbours, a ratio consistent with a regional access network purchasing transit and peering for customer connectivity.
  • Traffic from this AS consists of subscriber eyeballs and small business users in the Brescia region of Italy, utilizing the operator's cable and DSL infrastructure.

Notable

  • Registrants for two of the three announced prefixes (154.60.204.0/22 and 130.117.235.0/24) are listed as Cogent Communications, LLC, while the third (185.37.44.0/22) is registered to Nemo S.r.l., indicating the use of leased or historically allocated Cogent address space.
  • The inventory is composed of three distinct IPv4 blocks with no IPv6 prefixes announced, reflecting a legacy IPv4-centric deployment.

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: 447 networks and 1,843 prefixes, as published 2026-11-01. 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.
