Summary

TOTO LTD.

Japan · AI-generated

business japan corporate

TOTO is the AS handle for TOTO LTD., a Japanese corporation.

What it's used for

  • The address space is registered under the netname TOTOLAN with registrant IRT-JPNIC-JP, indicating a corporate allocation within Japan.
  • The AS announces a single IPv4 prefix, 157.12.0.0/16, comprising 65536 addresses, with 0 IPv6 prefixes.
  • With 1 observed neighbour, the routing profile suggests a limited peering footprint, consistent with an internal corporate estate or a small-scale business network rather than a transit provider.

Notable

  • The registrant IRT-JPNIC-JP aligns with the Japanese registry, supporting the identity of the holder as a domestic Japanese entity.
  • The inventory consists of a single contiguous /16 block, which is a standard allocation size for a mid-sized organization.
  • Secondary sources referencing the rock band "Toto" or the sanitary ware brand "TOTO" are distinct entities; the AS holder is specifically identified as TOTO LTD. in the registry data.

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: 453 networks and 1,848 prefixes, as published 2026-11-12. 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.
