Summary

Tsukaeru.net

Japan · AI-generated

hosting web apac

TSUKAERUNET is operated by JMF Investment & Technology PTY LTD, a web hosting company based in Japan.

What it's used for

  • The address space carries web hosting infrastructure, as indicated by netnames such as TSUKAERUNET-AS-AP, JMF, and TSUKAERUNET registered to the operator.
  • The AS announces 13,568 IPv4 addresses across 8 prefixes and 1 IPv6 prefix, with 13 observed neighbours, indicating a hosting provider with moderate peering relationships rather than a large transit or access network.
  • Traffic from this AS consists of web hosting services and API endpoints for clients in the APAC region, consistent with the operator's business focus.

Notable

  • Registrants for all major prefixes align with the announcer, listing IRT-TSUKAERUNET-JP and JMF Investment & Technology PTY LTD, except for 195.95.180.0/24 which is registered to Lukasz Sobon trading as SC Media Adam i Lukasz Sobon Sp. J. under netname PL-SCM-20060608.
  • The address inventory is composed of multiple /21 blocks and one /22, with a single /24 block that does not fit the primary Japanese allocation pattern.

Classification and threat

Hosting Datacenter or cloud provider. Addresses are servers, not people.

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: 431 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.
