Summary
Dream Wave Shizuoka
isp residential japan access
ACROSS is the AS handle for Dream Wave Shizuoka Co. Ltd., a regional internet service provider operating in Shizuoka, Japan.
What it's used for
- The address space carries residential and business access traffic, evidenced by reverse DNS entries such as
s-port.biz,client.s-cnet.ne.jp, andacross.or.jp. - With 48,640 IPv4 addresses announced across 34 prefixes and only 14 observed neighbours, the high address-to-neighbour ratio indicates an access or eyeball network rather than a transit provider.
Notable
- Registrants for the majority of prefixes are the Japan Network Information Center (JPNIC), consistent with the holder's identity as a Japanese ISP.
- Some prefixes, such as
43.229.244.0/22and45.113.4.0/22, are registered to different entities (engine-net,LLC and Bronze Arm LLC), suggesting leased space or historical acquisitions. - The inventory includes a mix of /20, /21, and /22 blocks, with netnames like
REDSPEEDandHypernet-Shizuokareflecting the operator's service brands.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 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.
