About this network

The AS handle has a space in it, which is unusual enough to be worth saying out loud.

What it's used for

• A manufacturer's network. Twenty-five IPv4 prefixes announced from the United States, no sixth-version space, eight thousand one hundred and ninety-two addresses, through thirteen observed BGP neighbours.

Notable

• The AS handle is the brand and a country short form separated by a space rather than a hyphen or nothing, where almost every handle avoids spaces entirely.
• Every block is registered to the holder, and the netnames come in two forms.
• Both begin with two letters for an internal technology department, then the brand, then the same country short form.
• The blocks in one parent range stop there. Those in the other add a four-letter short form of another company and a two-digit number.
• Eighteen addresses were queried for reverse DNS and none returned a name.

Interesting

• Putting a department's initials at the front of every netname is a company treating address space as an internal asset with an owning team, the same way a server or a licence would be tagged. It is a filing convention, not a network one.
• The extra short form on one range marks it as arriving with a business rather than being requested, and the department prefix was added in front afterwards to bring it into the house scheme.
• Thirteen upstreams on eight thousand addresses is a lot, and it fits a company whose machines sit in other people's offices worldwide.
