Summary

Open Solution S.R.L.

Italy · AI-generated

residential isp italy

OPENSOLUTION is operated by Open Solution S.R.L.

What it's used for

  • The address space carries customer access traffic, as indicated by reverse DNS entries such as 18-128.customer.opensolution.it and 16-64.customer.opensolution.it.
  • The network announces 768 IPv4 addresses across 2 prefixes and maintains a single observed neighbour, a ratio characteristic of an access or eyeball network rather than a transit provider.
  • Traffic from this AS consists of subscriber internet access for the Italian market, consistent with the operator's role as a local ISP.

Notable

  • Registrants for both announced prefixes are listed as OPEN SOLUTION S.R.L. or Abuse-C Role, aligning with the AS holder.
  • The address inventory is compact, consisting of two contiguous IPv4 blocks in the 185.249.16.0/22 range, with no IPv6 prefixes in inventory.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-08, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 455 networks and 1,854 prefixes, as published 2026-11-09. 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.
