About this network

An American brokerage announcing two blocks whose registrants are both carrier abuse desks, one of them overseas.

What it's used for

• An investment bank and brokerage's network. 512 addresses across two IPv4 prefixes, with four observed BGP neighbours and no IPv6 announced.

Notable

• 193.240.215.0/24 carries the netname STIFEL-NICOLAUS-COMPANY but is registered to LEVEL 3 COMMUNICATIONS - ABUSE.
• 213.68.255.0/24 carries VZ-213-68-255-0 and is registered to Abuse Verizon EMEA.
• Both blocks come from ranges administered outside the firm's own region.
• Six addresses were queried for reverse DNS and none returned a name.

Interesting

• Registrant fields pointing at abuse desks rather than organisations are how carriers file space they issue to customers in regions where the paperwork demands a contactable party. The result is that both records name somebody to complain to and nobody who uses the addresses.
• The first netname is the only place the firm is spelled out, and it is spelled out completely, which makes it the most useful field in either record.
• Four neighbours over 512 addresses is high, and for a brokerage that is the point: order flow and market data need paths that stay up, and address space is not what is being bought.
• Space administered in one region announced by a firm headquartered in another usually marks an overseas office or a trading presence that needed local addresses.
