Unclassified APNIC
Summary
Digital Alliance Co.,Ltd.
business japan ipv4
DA is the AS handle for Digital Alliance Co.,Ltd., a Japanese entity.
What it's used for
- The address space carries mixed business and legacy infrastructure, evidenced by netnames such as
CVKNET,YAMANASHI, andWINTECH-COM-CIDR-BLK-JP. - The AS announces 12,288 IPv4 addresses across 6 prefixes and 1 IPv6 prefix, with only 3 observed neighbours, indicating a small-scale access or internal corporate network rather than a transit provider.
- Reverse DNS entries like
93-host255.cvk.ne.jpsuggest the space hosts specific business endpoints or legacy systems associated with the CVK domain.
Notable
- All registrants are listed as Japan Network Information Center (JPNIC) with IRT-JPNIC-JP, which is standard for Japanese IP allocations and does not contradict the announcer's identity.
- The inventory includes diverse netnames (
DA-CIDR-BLK-JP,JPNIC-NET-JP,YAMANASHI,CVKNET,WINTECH-COM-CIDR-BLK-JP), suggesting the AS aggregates space from multiple historical or related entities. - The address inventory is finely subdivided into /20 and /22 blocks, consistent with an internal corporate estate or a small ISP managing distinct customer segments.

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: 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
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.
