Summary

OBIS Co.,Ltd

Japan · AI-generated

business japan ipv4

OBIS is the AS handle for OBIS Co.,Ltd.

What it's used for

  • The space carries corporate infrastructure, evidenced by the netname OBIS and registrant OBIS Co.,Ltd associated with the prefix 202.4.250.0/24.
  • The AS announces 256 IPv4 addresses and 1 IPv6 prefix, maintaining 5 observed neighbours, a ratio consistent with a small business or internal corporate estate rather than a transit provider.

Notable

  • The registrant OBIS Co.,Ltd and IRT IRT-OBIS-JP align directly with the AS holder, confirming ownership of the announced space.
  • The address inventory consists of a single /24 block in Japan, indicating a compact, self-contained network footprint.

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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
