Japan · AI-generated

isp exchange ipv6 residential

MF-NATIVE6-E is operated by Internet Multifeed Co.

What it's used for

  • The address space carries residential and shared user traffic, evidenced by reverse DNS entries such as shared.user.transix.jp and static.user.transix.jp.
  • The AS announces 67,584 IPv4 addresses across 5 prefixes and 2 IPv6 prefixes, while maintaining 18 observed neighbours; this ratio indicates an access network providing connectivity to end-users rather than a pure transit provider.
  • Traffic from this AS consists of subscriber eyeballs and residential broadband connections, as Internet Multifeed Co. operates the transix ISP service and JPNAP internet exchange.

Notable

  • Registrants for all announced prefixes are listed as Japan Network Information Center (JPNIC), which is consistent with the announcer as JPNIC is the registry for Japanese address space.
  • Internet Multifeed Co. is the operator of JPNAP, one of the largest internet exchanges in the world by traffic, and the transix ISP brand.
  • The inventory includes a mix of large blocks like 130.62.0.0/17 and smaller allocations, with significant IPv6 presence via 2404:8e00::/32 and 2409:10::/28.

Reputation

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: 442 networks and 1,773 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.
