AS9844 HANINTERNET-AS Duruan

AS9844 (HANINTERNET-AS) is registered to Duruan, a South Korean organisation. Beyond the registry record, public information about this holder is thin: the name does not map to a company with a visible web presence, and the registry handle (HANINTERNET) and the holder name (Duruan) do not obviously belong to the same brand. This card therefore sticks to what the routing evidence actually shows.

What it's used for

The network is about as small as a routed AS gets. RIS sees a single IPv4 prefix, 118.91.146.0/23 (512 addresses), no IPv6, and exactly one BGP neighbour. One prefix behind one upstream means this AS is single-homed: it is not multihoming for resilience, it is not peering with anyone, and it has no downstream customer cone. Whatever the AS number was originally obtained for, the network it describes today is a single small block of Korean address space reached through one provider.

A shape like this is usually one of two things: a small hosting or service business that keeps its own AS so it can move providers without renumbering, or a legacy registration that has outlived the network it was created for. The evidence available does not let us choose between those, so no functional claim is made here.

Notable

• The handle contains HANINTERNET, but a handle is not evidence of the operator's identity or line of business, and it should not be read as one.
• With one prefix and one neighbour, this AS is single-homed, which is unusual for a network that bothered to obtain an ASN.
