AS9524 HMC-AS Hyundai Autoever Corp.

AS9524 (HMC-AS-KR) is held by Hyundai AutoEver Corp., the IT and software affiliate of Hyundai Motor Group. AutoEver runs enterprise IT and systems integration for the group's companies, which is what this AS carries. The HMC handle points at Hyundai Motor Company, the group parent, not at a separate operator.

What it's used for

The routing evidence settles the role. RIS shows 83 IPv4 prefixes covering 27,136 addresses, no IPv6, and only 3 observed neighbours. The neighbour count is the decisive figure: a wholesale carrier holding this much space would peer with hundreds of networks, so a count of three means AS9524 buys transit from a small number of Korean carriers and sells connectivity to nobody. There is no customer cone here — every prefix serves the group.

The inventory says the same thing from the other direction. Two aggregates anchor the estate (58.87.32.0/19, 203.239.192.0/20 with 203.239.208.0/21), and the rest is a long tail of individually announced /24s clustered in 101.1.32.0–101.1.63.0, 58.87.x and 211.252.13x. Announcing dozens of adjacent /24s separately rather than as one aggregate is deliberate: it gives each affiliate, plant or site a discrete route that can be steered independently across upstreams. That is how a captive group-IT network is addressed.

Notable

• 27,136 addresses across 83 prefixes averages barely more than a /24 each — an estate assembled site by site, not a provider's pool.
• AutoEver covers in-vehicle software as well as enterprise IT, so this AS sits behind corporate systems rather than any consumer-facing product.
• No IPv6 is announced at all, despite the size of the IPv4 footprint.
