Unclassified ARIN
Summary
Equinix (EC-DC)
ixp cloud enterprise legacy
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.comandeqix-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
/24reads as a guest list. Theeqix-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.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,773 prefixes, as published 2026-10-13. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
