Unclassified ARIN
Summary
Prevare
hosting business enterprise
The one address that answers is labelled as a firewall, under a fourth company's domain.
What it's used for
- A managed services company's network. Five IPv4 prefixes announced from the United States, no IPv6, and two observed BGP neighbours.
Notable
- One of fifteen sampled addresses answered, and its host label says firewall, under a domain matching none of the companies in the record.
- Two blocks carry netnames made of a three-letter carrier prefix and a fifteen-digit number, the same billing-system format seen elsewhere in this range.
- Two other blocks are registered to a backup services company rather than the holder, one netname marking the protocol version and one written by a different provider entirely.
- The AS handle appends a town name and a state code to the company name.
- Five blocks, three registrants, four netname conventions.
Interesting
- Naming an address as a firewall in public DNS points at the device that enforces everything behind it. It is one lookup, it costs nothing, and it turns a scan of four thousand addresses into a scan of one.
- Four naming conventions across five blocks is what a managed services provider looks like from outside: each block came with a customer or a carrier, and the registry records the supply chain rather than the operator.
- The fourth domain in the reverse name is the most informative field here. It names a business none of the registry entries mention, which is the customer whose firewall sits on that address.

Internet exchanges
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 2026-10-17, 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 1,783 prefixes, as published 2026-10-17. 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.
