About this network

AS9957 (KINX-AS-KR) is held by KINX Inc., the carrier-neutral internet exchange and data-centre operator in Seoul. KINX runs Korea's carrier-neutral layer-2 IX alongside a set of internet data centres, a CDN, and cloud/interconnect products — so this ASN sits at the infrastructure layer, not the eyeball layer.

What it's used for

RIS sees 35 announced IPv4 prefixes totalling 12,800 addresses, no IPv6, and 77 observed BGP neighbours. The neighbour count is the tell. Seventy-seven peers on only ~12.8k addresses is far more BGP fan-out than an enterprise or campus of the same size would ever have, and it is exactly what you expect from a company whose business is interconnection: members and colocation customers of a neutral exchange end up adjacent to the operator's own AS.

The prefix list backs that up. One /20 aggregate (203.238.176.0/20) provides the bulk, and the remaining ~34 announcements are individual /24s scattered across 121.78/16, 1.201/16, 49.50/16, 182.161/16 and 139.150/16. Per-customer /24s carved out of several ranges is the normal inventory of a colocation and hosting provider assigning space to tenants, rather than a single organisation numbering its own users.

Notable

• KINX is a B2B infrastructure company: IX, IDC colocation, CDN, cloud and direct-connect to the major public clouds. Traffic in this ASN should be read as hosted and colocated services, not residential subscribers.
• An IX operator's peering LAN is a separate resource from its own AS — AS9957 is the company network, so peering-fabric addresses are not necessarily inside these announcements.
• Despite being an interconnection specialist, the ASN announces no IPv6 in RIS.
