About this network

AS9353 (MEDIAWARS) is held by Mediawars Co., Ltd., a small Kyoto company based in Kyoto Research Park. Its business is server hosting and colocation ("housing"), Internet connectivity, and — more recently — AWS design, migration and managed operations. The AS is the routed side of that hosting and provider business.

What it's used for

The footprint is small and stable. RIS observes 2 IPv4 prefixes — 210.233.64.0/20 and 103.247.84.0/22, about 5,120 addresses in total — no announced IPv6, and 2 BGP neighbours. Two upstreams and two blocks is the shape of a boutique hosting provider: enough address space to number customer servers and a couple of transit links for resilience, but nothing resembling the deaggregation of a service provider handing routed blocks to hundreds of customers, and nothing like the peering fabric of a carrier. The /20 is legacy APNIC space from the company's earlier ISP days; the 103.247.84.0/22 is a later, much smaller assignment, which is the normal trajectory for a Japanese provider that got its main allocation early and topped up afterwards. Reverse DNS matches: 210.233.64.5 resolves to ns.mediawars.ne.jp, the company's own nameserver, and 210.233.72.5 to www.intrabox.jp — a customer site living in the hosting space. Operator infrastructure plus hosted third-party web hosts is exactly what a colocation and web-hosting /20 should look like.

Notable

• The company still sells Internet connection service alongside hosting, so the space likely mixes colocated servers with a small number of business circuits.
• The named www. PTR on a customer domain is a positive marker of shared/dedicated web hosting rather than eyeball access.
• No IPv6 is announced.
