Summary

Japan · AI-generated

business japan fiber corporate

DIGITALBANK-JP is operated by Digitalbank, Inc., a regional ISP in Japan.

What it's used for

  • The address space carries corporate and fiber access infrastructure, evidenced by reverse DNS entries such as flets3-128.d-b.ne.jp, flets4-126.d-b.ne.jp, and prm3-254.d-b.ne.jp.
  • The AS announces 8192 IPv4 addresses across 9 prefixes with only 2 observed neighbours, indicating a small, self-contained internal corporate estate rather than a large-scale public access network.

Notable

  • Registrants for the majority of prefixes are listed as Digitalbank Corporation with netname DIGITALBANK-NET, which aligns with the AS holder DIGITALBANK, Inc..
  • The address inventory is finely subdivided into nine prefixes within the 202.143.224.0/20 range, with one /24 prefix (202.143.255.0/24) registered under the netname SANWANET with an unknown registrant.

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: 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.
