About this network

PROX is Prox System Design Inc., a hosting company in Taito-ku, Tokyo. It sells dedicated servers, VPS, colocation and domain registration, and brands its network services IXENT.

What it's used for

• Two prefixes, 210.143.96.0/20 and 210.166.208.0/20 — about 8,200 addresses. No IPv6 is announced.
• Reverse DNS is sparse, which is itself typical of server space: what resolves is infrastructure such as gwNNN.ixent.ne.jp, and the company's public services live on prox.ne.jp and ixent.ne.jp. There are no subscriber pools of any kind.
• Customer machines are the bulk of the space: rented dedicated servers and virtual private servers, plus co-located customer hardware in a Tokyo facility.

Notable

• A hosting network, small and single-purpose. Two contiguous /20s with no access addressing is the clean signature of a server business rather than an ISP, and the address space should be treated as datacentre space for geolocation and abuse purposes.

Interesting

• IXENT is the company's own coinage for its network side rather than any reference to an internet exchange — a handle that invites exactly the wrong reading. The company itself buys upstream transit and does not operate a peering fabric.
