fiber isp italy business

The AS handle FIBRAFAST-AS is held by Spadhausen SRL Unipersonale.

What it's used for

  • The address space carries fiber-to-the-home services, as indicated by the netname IT-SPADHAUSEN-SRL-20170124 and the registrant NOC Spadhausen.
  • The network announces 512 IPv4 addresses within a single /23 prefix (185.187.44.0/23) and maintains one observed neighbour, a ratio that indicates a local access network rather than a transit provider.
  • Traffic from this AS consists of residential and small business subscribers connected via fiber optic infrastructure in the Ravenna area of Italy.

Notable

  • The RDAP registrant NOC Spadhausen and the registry holder fibrafast-as Spadhausen SRL Unipersonale align, confirming consistent ownership of the address space.
  • The inventory consists of a single contiguous IPv4 block with no IPv6 prefixes announced, reflecting a focused deployment of IPv4 fiber services.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

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 1,852 prefixes, as published 2026-10-27. 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.
