Summary
AT-I, Inc.
isp cable dsl residential
AT-I-NET is operated by AT-I, Inc., a Japanese cable and DSL internet service provider.
What it's used for
- The address space carries residential and small business subscriber traffic, evidenced by reverse DNS records such as
host165-0.at-i.jpandhost-150.9.252.128.at-i.jp. - The AS announces 1,792 IPv4 addresses across 3 prefixes and maintains 5 observed routing neighbours, a ratio consistent with an access network providing last-mile connectivity rather than transit.
- Traffic from this AS consists of end-user internet access for subscribers in Japan, including web browsing, streaming, and general consumer internet usage.
Notable
- All registrants for the announced prefixes are listed as Japan Network Information Center (JPNIC) with the netname
AT-I-CIDR-BLK-JPorAT-I-NET, aligning with the AS holder AT-I, Inc. - The address inventory is composed of three distinct IPv4 blocks: 103.30.164.0/22, 150.9.252.0/23, and 219.100.252.0/24, all located in Japan.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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: 448 networks and 1,851 prefixes, as published 2026-10-29. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
