isp residential japan broadband

SNI-JP is operated by SNI (NetComBB Co.,Ltd.).

What it's used for

  • The address space carries residential broadband traffic, evidenced by reverse DNS entries for cableone.ne.jp, asunet.ne.jp, hachigamenet.ne.jp, and taku.ne.jp.
  • The AS announces 32768 IPv4 addresses across 6 prefixes and maintains 15 observed neighbours, a ratio consistent with an access network providing last-mile connectivity.

Notable

  • All registrants in the RDAP data align with the announcer, listing NetComBB Co.,Ltd. and the IRT IRT-SNIXBB-JP.
  • The address inventory is a contiguous block within the 61.7.0.0/16 range, subdivided into six prefixes of varying sizes from /18 to /22.

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: 436 networks and 1,771 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.
