AS3258 XTOM-JAPAN xTom Japan Corporation

XTOM-JAPAN is xTom Japan Corporation, the Japanese arm of xTom, an international hosting and IP-transit operator. It runs the company's Tokyo network.

What it's used for

• Dedicated servers, colocation and IP transit out of Tokyo data centres, on the operator's own routing platform.
• Tens of thousands of domains resolve into a relatively small number of hosts here, which is the signature of shared and virtual hosting.

Notable

• This is a hosting address. IPs here are servers and VPS instances, so outbound traffic is machine traffic. Anything that looks like a residential user from this range is worth a second look.
• The network peers at the major Tokyo exchanges and buys transit from several tier-1 and regional Asian carriers, giving it strong reach into both Japan and mainland China routes.

Interesting

• Despite the low number, this is not an early-internet network. xTom is a modern operator, and the ASN's history under this holder is much shorter than the number suggests. Low AS numbers in this range have often changed hands.
