About this network

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.
