Summary
StarNet
business japan ipv6
STARNET is the AS handle for StarNet Co.,Ltd., a Japanese network operator.
What it's used for
- The address space carries corporate infrastructure, evidenced by the reverse DNS entry
snc-net34.starnet.ad.jpand netnamesSTAR-Internet-CIDR-BLK-JPandSTARNET-1-CIDR-BLK-JP. - The AS announces 6144 IPv4 addresses across 2 prefixes and 15 IPv6 prefixes, with only 3 observed neighbours, indicating a business or internal corporate estate rather than a transit provider.
Notable
- Registrants for both IPv4 prefixes are listed as Japan Network Information Center (JPNIC), which is consistent with the announcer being a Japanese entity holding space through the national registry.
- The inventory is dominated by a large IPv6 allocation (2404:3200::/46 and sub-blocks) alongside a modest IPv4 footprint, suggesting a modernized network with significant IPv6 deployment.

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 2026-11-10, 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: 454 networks and 1,847 prefixes, as published 2026-11-11. 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.
