About this network

Two handles for one number, and neither is the company name.

What it's used for

• A company network. A single IPv4 /24 announced from the United States, no IPv6, and three observed BGP neighbours.

Notable

• The holder record prints the handle TRIOLAB beside the company name, while the AS handle field reads NSI. Two different identifiers describe the same autonomous system.
• The one block carries the netname NSI, matching the AS handle rather than the holder line.
• Three upstreams for one /24 is more connectivity than address space.
• Three addresses were queried for reverse DNS and none returned a name.

Interesting

• The mismatched handles are what a rename looks like when it is only half finished. One field was updated to an initialism of the current company name and the other still carries an earlier identifier that has nothing in common with it. Both are authoritative, both are served, and neither corrects the other.
• TRIOLAB is not an abbreviation of the holder name in any reading, so it almost certainly predates the company as it is named today. That makes it more useful for tracing history than the current name is.
• Three neighbours underneath 256 addresses is a lopsided shape. Networks that buy transit in three places usually have far more to carry, so the connectivity here is about staying reachable rather than about volume.
