About this network

An Equinix AS carrying interconnection space shared between customers of its exchange fabric.

What it's used for

• Shared interconnection. 1,024 addresses over four /24s, two IPv6 /48s, and ten observed BGP neighbours.

Notable

• Four prefixes, four unrelated owners. One is Equinix's own, EQUINIX-MA-DC. The others are registered to XPO Logistics, Philip Morris USA and Schaeffler Group USA — a freight broker, a tobacco company and a German bearings manufacturer's US arm.
• Reverse DNS on the Equinix block is the giveaway. Three sampled addresses answer as eqix-ema-dc.opentext.com, eqix-ema-dc.abb.com and eqix-ma-dc5.cscgovernment.com — three more companies, each naming its own address in its own domain.

Interesting

• This is what a shared interconnection LAN looks like from outside. Equinix hands each participant an address on a common subnet, and each participant publishes reverse DNS for it under their own name, so a single /24 reads as a guest list. The eqix- prefix on all three is the one thing they agreed on.
• The mix of tenants is the point of the business. Nothing connects a logistics firm, a cigarette manufacturer and a bearings maker except that all three needed private connectivity to cloud providers, and buying it through a colocation company's fabric is cheaper than building it. The routing table records the coincidence without explaining it.
