isp cable dsl okinawa

OCH-NET is operated by Okinawa Cross Head Co., Ltd.

What it's used for

  • The space carries residential access traffic, evidenced by the reverse DNS entry 5df66825103234178254.cu-mo.jp and the netname OCH-CIDR-BLK-JP.
  • The AS announces 1024 IPv4 addresses across 1 prefix (103.234.176.0/22) and maintains 10 observed neighbours, a ratio consistent with a regional access provider rather than a transit hub.
  • Traffic from this AS consists of subscriber eyeballs for cable and DSL services in the Okinawa region, as indicated by the operator's classification as a Cable/DSL/ISP.

Notable

  • The RDAP registrant for the announced prefix is Japan Network Information Center; IRT-JPNIC-JP, which is the standard registry holder for Japanese IP space and aligns with the announcer's location.
  • The address inventory is a single contiguous /22 block, indicating a compact and focused allocation for the operator's regional footprint.

Classification and threat

Residential Fixed-line consumer ISP. Addresses here are homes.

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: 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.
