Summary

business corporate japan
The AS handle EVONET is held by Sojitz Tech Innovation Co., Ltd.
What it's used for
- The address space carries corporate infrastructure, evidenced by the netnames
SOJITZ-NETandEVOnet-CIDR-BLK-JP. - The AS announces 69,632 IPv4 addresses across 2 prefixes while maintaining only 2 observed neighbours, a ratio that indicates an internal corporate estate rather than a transit or access provider.
Notable
- Registrants for both prefixes are listed as
IRT-JPNIC-JPorJapan Network Information Center, which aligns with the Japanese origin of the blocks and the holder's location. - The inventory consists of one large /16 block and one /20 block, representing a finely subdivided internal network structure typical of a major corporation.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-13, 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: 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
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.
