Unclassified APNIC Cable/DSL/ISP
Summary
Okinawa Cable Network
cable isp residential japan
The AS handle NIRAI is held by Okinawa Cable Network Inc.
What it's used for
- The address space carries residential and business customer traffic, evidenced by the reverse DNS record
sp-c-static27254.nirai.ne.jpand the netnameNIRAI-CIDR-BLK-JP. - The AS announces 18,432 IPv4 addresses across 4 prefixes and 1 IPv6 prefix, while maintaining 14 observed neighbours; this ratio of address space to peering partners is consistent with a regional access provider rather than a transit hub.
Notable
- All four announced IPv4 prefixes are registered to the Japan Network Information Center (JPNIC) under the netname
NIRAI-CIDR-BLK-JP, aligning the registrant data with the AS holder. - The operator is identified in peering databases as a Cable/DSL/ISP, confirming its role as a local internet service provider in Okinawa.
- The inventory consists of four distinct IPv4 blocks and a single /32 IPv6 prefix, indicating a focused regional footprint.

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: 447 networks and 1,852 prefixes, as published 2026-10-27. 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.
