Summary
ICNET
isp residential japan icnet
The AS handle ICNET is operated by JCOM Co., Ltd.
What it's used for
- The address space carries residential broadband traffic, evidenced by reverse DNS entries such as
g210002239254.d042.icnet.ne.jpandg114069171254.d214.icnet.ne.jp. - The network announces 20480 IPv4 addresses across 2 prefixes and maintains 1 observed neighbour, a ratio indicative of an access or eyeball network rather than a transit provider.
Notable
- The registrants for both announced prefixes are listed as Japan Network Information Center (JPNIC), which is consistent with the Japanese allocation authority for the operator.
- The address inventory consists of two distinct IPv4 blocks: 210.2.192.0/18 and 114.69.160.0/20, with no IPv6 prefixes currently in inventory.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-27, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
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: 447 networks and 1,852 prefixes, as published 2026-10-27. 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.
