residential isp italy dsl

The AS handle PIUDSL is held by PIU' DSL S.R.L.S.

What it's used for

  • The address space carries residential DSL and fibre subscriber traffic, evidenced by reverse DNS entries such as host185-139-183-64.piudslnet.it and host217-26-223-64.piudslnet.it.
  • The network announces 512 IPv4 addresses across 2 prefixes with 1 observed neighbour, a ratio indicative of a local access provider rather than a transit hub.
  • Traffic consists of end-user internet access for subscribers in the Santa Maria a Vico area of Italy, consistent with the operator's business as a regional ISP.

Notable

  • Registrants for both announced prefixes match the AS holder, listing PIU' DSL S.R.L.S and PiuDsl in the RDAP data.
  • The inventory consists of two /24 blocks, 185.139.183.0/24 and 217.26.223.0/24, with no IPv6 prefixes announced.

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