Summary
SIOPLUS
isp residential regional italy
SIOPLUS is operated by SIOPLUS S.R.L., a regional internet service provider based in Palermo, Italy.
What it's used for
- The address space carries residential and small business traffic, evidenced by reverse DNS entries pointing to
sioplusnet.it(e.g.,128-214-31-89.sioplusnet.it). - The AS announces 768 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, while maintaining 34 observed neighbours; this ratio of modest address inventory to high peering count indicates a regional access network rather than a large-scale transit provider.
- Traffic from this AS consists of subscriber eyeballs and local business endpoints served by SIOPLUS's regional infrastructure in Sicily.
Notable
- Registrants for both announced prefixes (
IT-SIOPLUS-20060922andIT-SIOPLUS-20200330) list Alessandro Cisilino, Alessandro Messina, and SIOPLUS S.R.L., aligning perfectly with the AS holder. - The address inventory is compact, consisting of one /23 and one /24 block, typical of a regional ISP managing a specific local footprint.

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: 449 networks and 1,846 prefixes, as published 2026-11-03. 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.
