Summary

Frankenmuth Mutual Insurance Company

United States of America · AI-generated

insurance business corporate internal

The AS handle FMIC is held by Frankenmuth Mutual Insurance Company.

What it's used for

  • The address space carries internal corporate infrastructure, evidenced by reverse DNS entries pointing to id.fmins.com and netnames DR-SITE-01 and FHO.
  • The network announces 512 IPv4 addresses across 2 prefixes with only 1 observed neighbour, indicating a small, self-contained internal estate rather than a transit or access provider.

Notable

  • Registrants for both announced prefixes match the AS holder, Frankenmuth Mutual Insurance Company, confirming direct ownership of the address space.
  • The inventory consists of two /24 blocks, 130.51.126.0/24 and 204.145.176.0/24, representing a modest footprint typical of a mid-sized corporate network.

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 1,778 prefixes, as published 2026-10-20. 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.
