Unclassified APNIC
Summary

business enterprise hosting
Five blocks, five netnames, and at least five company names between them.
What it's used for
- A consulting group's network. Five IPv4 prefixes announced from Italy, no IPv6, one thousand seven hundred and ninety-two addresses, across three observed BGP neighbours.
Notable
- The AS handle is the brand in capitals, then the same brand in mixed case, then the words for an autonomous system spelled out.
- Two blocks use that brand as the netname. The other three use a valley-themed name, a code ending in two digits, and a two-letter-plus-digit abbreviation with the word for a network.
- The contacts name a network operations centre, the parent consulting firm, a brand with a digit in front of it, a second brand in capitals, and a network services company, so five names appear across five blocks.
- Two registrants are companies whose legal forms are the abbreviations used in a different country from the one the blocks are announced in.
- Fifteen addresses were queried for reverse DNS and none returned a name.
Interesting
- Consulting groups grow by buying practices and keeping their names as brands, and the registry ends up as the list of what was bought. Each block here is an acquisition that came with its own addresses and its own operations team.
- A handle that writes the brand twice in two casings before spelling out what an autonomous system is suggests a form completed by someone who was not sure which part was the answer.

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-15, 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: 442 networks and 1,782 prefixes, as published 2026-10-16. 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.
