isp residential japan cable

The AS handle EXTRIDE-NET is held by Extride Inc., a regional internet service provider based in Hitoyoshi, Kumamoto, Japan.

What it's used for

  • The address space carries residential and business subscriber traffic, evidenced by reverse DNS entries like 254-82-99-103.extride.ad.jp and 190-246-199-170.extride.ad.jp.
  • The network announces 6,400 IPv4 addresses across 4 prefixes and maintains 16 observed neighbours, a ratio consistent with an access network providing last-mile connectivity rather than transit.
  • Traffic from this AS consists of subscriber eyeballs and local business endpoints served by Extride's cable and DSL infrastructure in the Kyushu region.

Notable

  • All registrants for the announced prefixes are listed as Japan Network Information Center (JPNIC) with the netname EXTRIDE-CIDR-BLK-JP, aligning with the AS holder.
  • The address inventory is composed of four distinct IPv4 blocks, including a /20 and three smaller prefixes, with no IPv6 prefixes currently announced.

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: 445 networks and 1,817 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.
