About this network

The AS is filed under a handle that names a cabinet in a particular exchange building.

What it's used for

• A financial technology company's network. 4,096 addresses across seven IPv4 prefixes, with three observed BGP neighbours and no IPv6 announced.

Notable

• The AS handle is ITHS-NY4-BLK-001, which matches neither the company name nor any netname on its blocks.
• Five of the seven blocks share the single netname OFSL-5; a sixth carries ONEZERO-ADDRESS-BLOCK-1.
• 38.76.4.0/24 is registered to Cogent Communications, LLC under COGENT-A.
• Eighteen addresses were queried for reverse DNS and none returned a name.

Interesting

• That handle reads as a facility, a building code and a numbered block. The building code in the middle is one of a handful of addresses in the financial world that everyone in the industry can name from memory, because being inside it is the difference between a trade arriving first and arriving second. The AS was registered by whoever ran the cage, and the name stuck.
• Five blocks under one netname numbered five is a company that filed once, was given space repeatedly, and reused the same label. The sixth block breaks the pattern with a fully spelled-out name, which is what happens when a different person does the paperwork.
• One block is the carrier's own space, announced by the customer. That is how a provider hands out a small assignment without the customer having to justify it to a registry.
• Nothing answers a reverse lookup across eighteen addresses, which for trading infrastructure is the point.
