AS14812 — CNSX-PRIMARY

AS14812 announces 1 IPv4 prefixes covering 512 addresses and 0 IPv6 prefixes.

About this network

Ten upstreams for a single block of 512 addresses, and none of the addresses are its own.

What it's used for

• A stock exchange's network. 512 addresses in a single IPv4 prefix, with ten observed BGP neighbours and no IPv6 announced.

Notable

• The whole footprint is 38.64.246.0/23, carrying the netname COGENT-A.
• That block is registered to Cogent Communications, LLC, not to the exchange.
• The AS handle is CNSX-PRIMARY, which implies a second number somewhere.
• Three addresses were queried for reverse DNS and none returned a name.

Interesting

• Ten neighbours is the highest count in this part of the range, and it sits on the smallest sort of network. An exchange is judged on whether participants can reach it during the trading day, so the sensible design is many paths into a very small target. Most businesses buy bandwidth; this one is buying independent ways in.
• Holding no address space of its own is the other half of the same trade. The AS number is what makes the many paths possible; the addresses are borrowed and would be renumbered if the provider changed. Independence where it matters, paperwork avoided where it does not.
• The word primary in the handle is the kind of label that only makes sense beside a secondary. Its counterpart is not visible here, which is what you would expect of a backup that is announced only when needed.
• Nothing published in reverse DNS suits a network whose users all connect by prior arrangement.
