AS9226 SGIX-AS-AP 1-Net Singapore Pte Ltd

AS9226 (SGIX-AS-AP) is held by 1-Net Singapore Pte Ltd, a carrier-neutral data centre and managed services operator in Singapore and an enterprise of the Mediacorp group. The -IX in the handle is a legacy label and should not be read as meaning the AS is an Internet exchange: it is 1-Net's own routed address space.

What it's used for

The evidence points at a colocation and managed-hosting network. RIS sees 5 IPv4 prefixes carrying 30,720 addresses, plus a single large IPv6 allocation, 2402:2400::/33. What stands out is how the space is shaped: three /19s, a /20 and a /21, announced whole rather than sliced into dozens of small pieces. Clean aggregates of this size are what a facility operator announces when it assigns blocks to colocation tenants and managed customers out of its own space, rather than an access network handing out addresses to thousands of individual subscribers.

The 10 observed neighbours are consistent with that role. A data centre operator needs good regional connectivity and a handful of upstreams and peers, but it does not sell wholesale transit at scale, so it never accumulates the hundreds-to-thousands of BGP adjacencies a carrier does. A /33 of IPv6 is also a notably generous allocation for a network of this IPv4 size, which fits an operator that expects to sub-delegate to tenants.

Notable

• 1-Net operates carrier-neutral data centres in Singapore and is owned by Mediacorp, Singapore's national media group.
• The SGIX handle is a name collision waiting to happen: Singapore does have an Internet exchange called SGIX, and it is a different organisation from the holder of this ASN.
