Summary
Mixi
social business japan
MIXI is operated by Mixi, Inc.
What it's used for
- The address space carries corporate infrastructure for a Japanese social networking service, as indicated by the netname
Mixi-CIDR-BLK-JPon all announced prefixes. - The AS announces 5,120 IPv4 addresses across 3 prefixes and 1 IPv6 prefix, with only 2 observed neighbours, indicating a small-scale internal corporate estate rather than a transit or access network.
- Traffic from this AS consists of web and API endpoints for the mixi social platform, supporting user interactions and service delivery for its subscriber base.
Notable
- All registrants for the announced prefixes are listed as Japan Network Information Center; IRT-JPNIC-JP, which is consistent with the announcer being a Japanese entity.
- The address inventory is compact and finely subdivided into three distinct IPv4 blocks, reflecting site-by-site segmentation typical of a corporate network.

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.
