AS14969 announces 11 IPv4 prefixes covering 3,328 addresses and 0 IPv6 prefixes.

About this network

Eleven blocks in three regions, a netname containing a date from 1992, and nothing published anywhere.

What it's used for

• A trading firm's network. 3,072 addresses across 11 IPv4 prefixes, with 13 observed BGP neighbours and no IPv6 announced.

Notable

• The blocks are registered in three regions: JSCL-1 and carrier-issued space in one, a country-prefixed carrier netname and UK-JANESTREET-19920228 through a European provider, and JANE-HK with an incident response contact in another.
• One block is labelled with a carrier's name alongside the firm's, under that carrier's own incident response team.
• Eighteen addresses were queried for reverse DNS and none returned a name.

Interesting

• Ten of the eleven announcements are a single /24, the smallest block most of the internet will carry, and each sits in a different part of the address space. That is a firm putting one small presence next to each market it trades on, because the machine has to be in the building where the exchange is.
• One netname ends in a date from long before the company existed. That block was assigned to somebody else in the early nineties, changed hands, and kept the label with the original allocation date frozen into it.
• Contacts registered as incident response teams rather than individuals are a requirement in some regions and a good idea in all of them. The record is built to survive staff turnover.
• Thirteen neighbours against three thousand addresses is the ratio that gives the game away: connectivity matters far more here than address count. Nothing is published in reverse DNS because nothing here is meant to be found.
