AS9989 EQUINIX-AP Equinix Singapore Pte Ltd

AS9989 (EQUINIX-AP) is held by Equinix Singapore Pte Ltd, the Singapore entity of Equinix, the global colocation and interconnection operator. It is the company's Asia-Pacific corporate AS, not the AS behind the Equinix Internet Exchange route servers, and not a transit product.

What it's used for

The inventory is deliberately small and infrastructure-shaped. RIS sees 5 announced IPv4 prefixes totalling 1,280 addresses, one IPv6 prefix (2403:b100::/33), and 2 observed BGP neighbours. Four of the five v4 prefixes are a contiguous run of /24s out of 103.55.124.0/22 plus a legacy 202.177.206.0/24; the fifth, 51.162.156.0/24, is drawn from RIPE-administered space rather than APNIC's, which is the kind of cross-RIR holding a multinational accumulates as it acquires businesses and consolidates address resources.

A colocation company's own AS carries the things the company runs rather than the things its customers run: management and portal systems, the network services it sells into its facilities, and the addressing that anchors its own presence in the exchanges it operates. Customer traffic in an Equinix building is carried by the customers' own ASes, so a footprint of ~1,280 addresses is exactly what you would expect here and says nothing about the scale of the business.

Notable

• The RIPE-registered 51.162.156.0/24 under an APNIC-registered AS is worth a second look for anyone geolocating this space, since the registry region and the announcing AS disagree.
• Equinix's exchange fabric peering LANs and route servers live under separate AS numbers; do not read this one as the IXP.
