ARCOLINK-ASN is operated by Arcolink Telecomunicazioni S.r.l.

What it's used for

  • The address space carries static residential and business connections, evidenced by reverse DNS entries such as host-0-static-132-174-217.net.arcolink.it and netnames like IT-ARCOLINKTLCSRL-20140519.
  • The AS announces 9,728 IPv4 addresses across 6 prefixes and 3 IPv6 prefixes, with 78 observed routing neighbours.
  • Traffic consists of subscriber internet access via Arcolink's Fixed Wireless Access (FWA) network, providing broadband connectivity to end-users in the Tuscany region.

Notable

  • Registrants for the largest prefixes include Arcolink-NOC and BALICATRADE SOCIETA' A RESPONSABILITA' LIMITATA SEMPLIFICATA, indicating the space includes assets originally registered to Balicatrade before consolidation under Arcolink.
  • The inventory is composed of multiple /22 and /21 blocks, reflecting the acquisition of address space from different sources over time.

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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
