Summary
Kakaku.com, Inc.
business web japan
KAKAKUCOM is the autonomous system for Kakaku.com, Inc., a Japanese internet company operating the Kakaku.com price comparison website and other digital services.
What it's used for
- The address space carries the company's web infrastructure, with all three IPv4 prefixes registered under the netname
KAKAKUCOMvia the Japan Network Information Center. - The AS announces 3,072 IPv4 addresses across 3 prefixes and 1 IPv6 prefix, maintaining 7 observed neighbours; this low neighbour count relative to the address inventory indicates a business network rather than a transit provider.
- Traffic from this AS consists of web and API endpoints serving the company's comparison shopping platform and related online services.
Notable
- All registrants for the announced prefixes are listed as the Japan Network Information Center with the netname
KAKAKUCOM, consistent with the AS holder. - The address inventory is compact, consisting of three /22 IPv4 blocks and a single /32 IPv6 prefix, typical of a corporate web presence.

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: 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.
