About this network

An exchange holding company whose addresses all answer under an IT provider's domain.

What it's used for

• An options exchange holding company's network. A single IPv4 /24 announced from the United States, no IPv6, and one observed BGP neighbour.

Notable

• The AS handle is the company's initials, a counter and then the AS number itself, so the identifier contains its own name.
• All three sampled addresses answered, each with the address written out in dashes under a managed IT provider's domain, a company the registry never mentions.
• The netname is the same initials and counter as the handle, without the AS number.
• Three addresses were queried for reverse DNS and three returned a name.
• Two hundred and fifty-six addresses behind a single upstream.

Interesting

• Reverse DNS naming a provider rather than the holder tells you who runs the network. The exchange holds the registration; somebody else operates the addresses and writes the zone.
• An AS handle ending in its own AS number is a small circularity that shows up more than once in this range. It happens when the registry requires a unique handle and the obvious name is taken.
• A financial exchange group announcing one block through one upstream is a modest footprint for the business. Trading systems live on private circuits, not on the public routing table, so what shows here is the corporate edge rather than the market.
