The AS handle TOP-IX_DP is held by Consorzio TOPIX - Torino e Piemonte Exchange Point.

What it's used for

  • The address space carries infrastructure for the TOP-IX Internet Exchange Point, with netnames such as IT-TOP-IX-941130 and IT-TOP-IX-20160226 registered to the Consorzio TOPIX NOC.
  • The AS announces 11,776 IPv4 addresses across 9 prefixes and 1 IPv6 prefix, while maintaining 95 observed neighbours, a ratio indicative of a transit or peering hub role rather than a residential access network.
  • Traffic from this AS consists of peering sessions and transit flows for members of the TOP-IX exchange point in the Turin and Piedmont region.

Notable

  • All registrants for the announced prefixes are consistent with the announcer, listing CONSORZIO TOPIX - TORINO E PIEMONTE EXCHANGE POINT; TOP-IX NOC.
  • The address inventory is concentrated in the 194.116.0.0/16 range, with a single /24 in 193.42.0.0/16 and a /22 in 185.140.0.0/16.

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: 442 networks and 1,779 prefixes, as published 2026-10-21. 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.
