Summary
Mieden Co.,Ltd.
business japan corporate
MIEDEN-NET is the autonomous system for Mieden Co.,Ltd.
What it's used for
- The address space is registered under the netname
MIEDEN-NET-CIDR-BLK-JP, indicating a dedicated corporate allocation for the company's internal infrastructure. - The AS announces 768 IPv4 addresses across 2 prefixes with 2 observed neighbours, a ratio consistent with a small-scale business network rather than a transit or access provider.
Notable
- The RDAP registrants for both prefixes are listed as Japan Network Information Center; IRT-JPNIC-JP, which is the standard registry for Japanese IP space and does not indicate a mismatch with the announcer.
- The inventory consists of two contiguous IPv4 blocks: 202.78.248.0/23 and 202.78.250.0/24, with no IPv6 prefixes announced.

Interconnection
Peering at a glance
Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-13, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
