AS38628 WINK-NET HIMEJI CABLE TELEVISION CORPORATION
Unclassified APNIC Cable/DSL/ISP
Summary
WINK
cable isp residential japan
WINK-NET is operated by Himeji Cable Television Corporation.
What it's used for
- The address space carries residential cable broadband traffic, evidenced by reverse DNS records pointing to
ip4.winknet.ne.jpand netnames such asWINK-NET3,WINK-NET4, andWinknet-CIDR-BLK-JP. - The AS announces 77,824 IPv4 addresses across 15 prefixes and 1 IPv6 prefix, while maintaining 19 observed neighbours; this ratio of high address volume to moderate peering indicates an access network serving end-users rather than a transit provider.
- Traffic from this AS consists of subscriber eyeballs for residential internet access in the Himeji and surrounding Hyogo prefecture region of Japan.
Notable
- Registrants for the majority of prefixes are listed as
Japan Network Information Centerwith IRTIRT-JPNIC-JP, which is consistent with standard Japanese IP allocation practices where JPNIC holds the registry records for local operators. - One prefix,
163.131.64.0/19, carries the netnameIIJ-CIDR-BLK-JP, suggesting a portion of the address space may have originated from or is associated with Internet Initiative Japan, though it is currently announced under WINK-NET. - The inventory includes a mix of /17, /19, /20, /21, /22, and /23 blocks, with the largest being
45.75.0.0/17.

Reputation
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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
