Summary
NTT DoCoMo
isp mobile eyeball
NTT DoCoMo (DOCOMO) — Japan's largest mobile carrier, part of the NTT group.
What it's used for
- Mobile data for a very large Japanese subscriber base, plus DoCoMo's related online services.
Notable
- A large "eyeball" network; addresses here are typically Japanese mobile devices, often behind carrier-grade NAT, so geo is coarse.
- One of Japan's three big carriers alongside KDDI (au) and SoftBank.
Interesting
- DoCoMo pioneered mobile data early with its i-mode service in the late 1990s, years ahead of the smartphone era.

Classification and threat
Mobile Cellular carrier. Addresses are shared by many handsets via CGNAT.
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: 440 networks and 1,773 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
1 IC3 indicators addresses in this network appear in FBI IC3 cybersecurity advisories.
| Prefix | Advisory | Published |
|---|---|---|
110.163.142.168 | China-Linked Hacking Group QTFY Targets Military and Critical Infrastructure with Malicious Distributed Systems | 2026-08-26 |
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
