Summary
xTom Japan Corporation
hosting legacy
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.

Classification and threat
Hosting Datacenter or cloud provider. Addresses are servers, not people.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 436 networks and 1,771 prefixes, as published 2026-10-13. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
2 IC3 indicators addresses in this network appear in FBI IC3 cybersecurity advisories.
| Prefix | Advisory | Published |
|---|---|---|
103.201.131.121 | China-Linked Hacking Group QTFY Targets Military and Critical Infrastructure with Malicious Distributed Systems | 2026-08-26 |
103.125.234.14 | #StopRansomware: Gunra Ransomware | 2026-08-10 |
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
